* Fixes#4632.
* 1:27 am coding best coding
* fixes a warning
* Removes the last of the gender macros. Gender is dead.
* gender II: the travis-ing
* linebreaks are dead too.
* oops i accidentally the gender, also ambiguous gender is now taken into account for get_visible_gender
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.
* Creating new objects is cheap, in fact comparable to the cost of getting it out of the pool, so it doesn't help there.
* Placing items in the pool is far more expensive than letting them garbage collect due to the resetting of vars and such.
* Makes the paper shredder constructable and deconstructable.
* Switches to some new sprites which are animated!
* Machine now requires power, icons respond to power on/off etc.
A lot of new defines are now in inventory_sizes.dm, which contains;
All the size identifiers (the thing that tells the game if something is bulky, or w/e).
Storage costs for all the sizes, which are exponents of two, as previously.
A few constants for inventory size.
Also changes all storage item's capacity definitions by basing it off of how many 'normal slots' exist for it. This allows one to change the definition for all of the defines in the file, and everything will follow along without needing to change 500 files. In testing, I made all ITEMSIZE_COST_* defines doubled, and nothing had broke.
The benefit of doing all of this is that it makes adding new weight classes in the future much simpler, and makes knowing how much space a container has easier, as seeing ITEMSIZE_COST_NORMAL * 7 means it can hold seven normal items.
