Custom gear loadouts.

Adds custom loadouts to character generation and spawning. Each character slot can contain a list of 5 points worth of datums from preferences_gear.dm. Some are whitelisted for aliums, some are restricted to specific jobs. Items will attempt to spawn to a slot (prior to job-specific gear spawning, hence overwriting it) as defined in their datum, or if no slot is defined, your backpack (or internals box if you have no backpack).

Some incidental shit also included:
- Moved roundstart mining distribution map and spawnpoints into a better place.
- Fixed minor issue preventing spawnpoint from saving.
- Corrected a few small typos in some clothing.
- Added Zhan-Khazan furs and headscarf.
- Moved Armalis communion verb to humans, added to Vox Armalis species datum, deleted unused/unneeded simple_animal armalis definition.
