Simple animals now use the base health system that most other mobs use.
Fixes a bunch of Destroy()s so that they should qdel properly.
Mend Synthetic can heal synthetic simple animals.
Adds attack and spellcast animations to the golem.
Adds system to manually flick because byond is stupid sometimes.
Removes shield and reflect spells from the golem since SAs can't use shields at the moment.
Adds more helpful spells to the golem.
Golem and the Lost Drone now use the 'synthetic_evil' speech bubble.
* 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.
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.
