* This is PHASE 1 of a multi-phase conversion. In this first phase we implement the subsystem, but leave it processing the existing global list variables. In the next phase we will switch to use datum variables in the subsystem. The main reason for splitting into two phases is ease of code review; change the meaningful code without the hundreds of machines -> SSmachines.machinery substitutions.
* We did declare macros for adding/removing things to the processing lists, and convert everywhere to use the macros.
* Added var/is_processing to /datum to keep track of whether an instance is already in a processing list (prevents it being in the list twice!) and also debugging, making sure its not in two lists etc.
* NOTE: The global machines list is **no longer sorted** for performance reasons. As far as I know, the only module that actually ever cared was cameras. Our camera system already handles its own sorting in the cameranets anyway, so it should no longer be needed.
Adds toolspeed var, which is a multiplier on how 'fast' the tool works. 0.5 means it goes twice as fast.
Adds usesound var, which determines what sound is used when a tool is being used.
Changes a lot of code to use those two vars instead.
Adds 'ayyy' tools, which are ported from /tg/'s abductor gamemode. They're currently admin only but I might make them obtainable by xenoarch later.
Adds powertools, also from /tg/. CE starts with them in a new toolbelt that spawns in their locker, ported from (you guessed it) /tg/.
Changes welder sprites to look nicer, ported yet again from /tg/. Modified the blue welder slightly so it can be the electric welder sprite.
Adds various sounds from /tg/, for tools and welders.
* Remove remaining hard del()'s in our code.
* Replace deleted() and gcDestroyed with QDELETED macro.
* Fix some strange calls directly to Del() (capital D)
* Make Destroy() return qdel hints.
* Make a few of the Destroy()'s more comprehensive in cleaning up references.
* In edited Destroy() procs, converted to use qdel_null and qdel_null_list macros when possible for pretty code.
* Removed unused variable `sleevecard`
* This device converts CO2 to O2 using power and "algae". The extra carbon is a byproduct in the form of "graphite"
* This is intended for virgo3b, which has no oxygen in its atmosphere but enough CO2 for us to just extract it.
I have no idea why this is in the code.
Its unobtainable in game and would be difficult to create even with
admin powers, as there's no canister to spawn it in or anything like
that so you'd have to VV an already existing gas.
* Removes text2path, adds constructability to a few things, adds a locker_painter.dm, and several fixes.
* Fixes Maps due to working on ancient versions.
* Path error.
* Adds a missing ..()
