elly1989@rocketmail.com 6e274cd395 New lighting, it's essentially just the old DAL system with a queue. 
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.

/* This is an attempt to make some easily reusable "particle" type effect, to stop the code
constantly having to be rewritten. An item like the jetpack that uses the ion_trail_follow system, just has one
defined, then set up when it is created with New(). Then this same system can just be reused each time
it needs to create more trails.A beaker could have a steam_trail_follow system set up, then the steam
would spawn and follow the beaker, even if it is carried or thrown.
