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.
Someone had added shower curtains to the map. Creates proper definitions to avoid colors being lost on cleaning.
Floor corner decals now all utilize a white base state and simply apply a color.
