Testing has revealed that it reduces the sluggishness of the game, though it will spike from lag when the singularity is loose. Thanks to ChuckTheSheep for suggesting it.
Server owners who want to keep set background enabled can do so by changing the define.
-Removed the priorityqueue datum. It is now a list()
-priorityqueue/proc/insert is now a helper /proc/sorted_insert() as it may be helpful in maintaining pre-sorted lists or insertion sorts.
-Replaced priorityqueue/proc/extract_last() calls with calls to pop(), which already existed.
-Removed last few references to "bestF" (from old awful A) in lighting and MC
-Replaced a section were it'd append to the end of the returned path list and then reverse the list. Now it inserts at the start of the list.

> UpdateAffectingLights() is a bit less silly. It now uses oview() to find lights which could be shining on it. It only searches a maximum of LIGHTING_MAX_LUMINOSITY_STATIC-1 away from itself, as this is all it needs to do (reducing the number of atoms it searches/lights it updates).
> UpdateAffectingLights() is called more sensibly, generally it will only be called when opacity actually changes on a lit turf (or something in a lit turf), as opposed to before where it would be called simply if something was opaque.
> Fixes a typo in cheap_hypotenuse(), it will now work correctly.
> Added circular lighting (using cheap_hypotenuse, a cheap linear approximation of pythagoras theorem). Old square lighting is toggable by commenting out #define LIGHTING_CIRCULAR
> Wall-fixed lighting will break when Move()ed. This means their lighting will not be updating whilst the singulo is on a rampage (which would cause lots of lighting updates). This should help reduce lighting updates a fair bit in such circumstances. Also the lord of darkness actually creates darkness! omg
>Halved the theoretical number of calls to UpdateAffectingLights() by turfs being deleted/created (aka replaced), by moving relevant code from New/Del into ChangeTurf(). Tidied ChangeTurf up a little.
>SpaceVines now update opacity correctly (this somewhat worries me though)
>Reduced the range of dynamic lighting effects for most objects. Fixed the bug where mob luminosity could try to go negative when dropping many held active flashlights.
>Space area no longer uses dynamic lighting. (at request)
>Fewer shades of darkness (reduced from 7 to 6) - means fewer shift_to_subarea calls and makes lower luminosity lights appear brighter
>Turfs can be luminous, removed the warnings. capped luminosity effects of turfs to a radius of 1.
>PDAS ARE NO LONGER SUNS!
>ChangeTurf() no longer replaces turfs with turfs of the same type. This means that singulos will no longer replace space with space with space over and over and over every tick
>there is a cpu-usage cap thingy on the lighting process(). It's currently set to (a ridiculously high) 98. This simply stops the process attempting to do any more work when the server is already dying. If you're feeling brave you could probably reduce further.

Fixed a problem where TG was using this sequential master_controller but I had removed a spawn where master_controller.process() was called because I was working with the default master_controller. This problem was causing the master_controller to prevent the lighting_controller.process() ever running properly because it was hogging the current thread (thread isn't the right word there, not sure what you call it....stack?)
Added debugging to both the lighting_controller and master_controller. http://filesmelt.com/dl/debugging.png
Both lighting_controller and master_controller may be deleted to terminate their processes (this is done via the restart controller verb. This allows for clean restarts without 'doubling up' (where, for instance, the master_controller would be running more than one instance).
lighting_controller has a prototype recovery proc which is called by the "restart controller - lighting" verb. It's basically an overly paranoid version of process() which will only transfer light_sources to the replacement controller if they don't runtime. It's not needed at the moment as the process() has yet to runtime.
master_controller has the beginnings of self pruning lists. This method using list.Cut(index,index+1) is faster than doing list.Remove(thing) all over the place (the latter iterates through the list to find the thing).
Added more detailed time-measurements for the master_controller. It now displays the processing costs (in real-world seconds) of each part of the master_controller's cycle.
The stat panel only updates for mobs actually -looking- at the stat panel.
Explosion debugging is now hidden behind a if(Debug2). To have it print that data to world.log just click the DebugGame verb
debug controller and restart controller verbs are now both GameAdmin rank. Not sure how they got split up.
Fixed another cause of dark splotchy space turfs. (turf/wall/ex_act was replacing the turf with space and then deleting that new space turf)

Reduced the Login delay for new_players. It stays because it protects against rapid connect/disconnects sending resources repeatedly, it's just a lot less annoying now.

Comments for lighting:
Like sd_DAL (what we used to use), it changes the shading overlays of areas by splitting each type of area into sub-areas
by using the var/tag variable and moving turfs into the contents list of the correct sub-area.
Unlike sd_DAL however it uses a queueing system. Everytime we call a change to opacity or luminosity
(through SetOpacity() or SetLuminosity()) we are simply updating variables and scheduling certain lights/turfs for an
update. Actual updates are handled periodically by the lighting_controller. This carries additional overheads, however it
means that each thing is changed only once per lighting_controller.processing_interval ticks. Allowing for greater control
over how much priority we'd like lighting updates to have. It also makes it possible for us to simply delay updates by
setting lighting_controller.processing = 0 at say, the start of a large explosion, waiting for it to finish, and then
turning it back on with lighting_controller.processing = 1.
Unlike our old system there is a hardcoded maximum luminosity. This is to discourage coders using large luminosity values
for dynamic lighting, as the cost of lighting grows rapidly at large luminosity levels (especially when changing opacity
at runtime)
Also, in order for the queueing system to work, each light remembers the effect it casts on each turf. This is going to
have larger memory requirements than our previous system but hopefully it's worth the hassle for the greater control we
gain. Besides, there are far far worse uses of needless lists in the game, it'd be worth pruning some of them to offset
costs.
Known Issues/TODO:
admin-spawned turfs will have broken lumcounts. Not willing to fix it at this moment
mob luminosity will be lower than expected when one of multiple light sources is dropped after exceeding the maximum luminosity
Shuttles still do not have support for dynamic lighting (I hope to fix this at some point)
No directional lighting support. Fairly easy to add this and the code is ready.
When opening airlocks etc, lighting does not always update to account for the change in opacity.
Explosions now cause lighting to cease processing temporarily.
Moved controller datums to the code/controllers directory. I plan on standardising them.
"Master","Ticker","Lighting","Air","Jobs","Sun","Radio","Supply Shuttle","Emergency Shuttle","Configuration","pAI" controller datums can be accessed via the debug controller verb (used to be the debug master controller verb)
Supply shuttle now uses a controller datum. Shuttles tend to arrive up to 30 seconds late, this is not a bug.
