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.
* Adds hacking tool.
In normal mode a hacking tool acts and functions just like any multitool. Use a screwdriver to toggle between normal and hacking mode.
Hacking attempts will take 20 +(0 to 20) seconds (triangular distribution, averages at +10 seconds).
Once an airlock has been successfully hacked the user will have full access to the door operation interface normally restricted to silicons.
A hacking tool will remember the last 6 to 8 hacked airlocks. No time is needed to again hack remembered airlocks.
Once the limit has been reached the least recently accessed airlock is forgotten. Hacking a remembered airlock will update the last accessed time.
Also adds a basic observer/listener pattern implementation to, for example, make it easier to catch when objects have been destroyed and clear references.
* Corrects and adds more sanity checking.
* Adds hacktool to uplink devices
