TG: - Removed support for the ONBACK and ONBELT flags.

- Replaced them with a whole range of inventory slot flags. These now govern
whether an item can or can't be placed in a certain inventory slot. See setup.dm
for information on the flags. These flags only affect humans tho, as humans are
the only beings with an inventory to talk of.
- Standardized some gun code and some other pieces of code as I came accross
them. I hate indented variable definitions!

This commit should not bring any change whatsoever to the game from a player's
perspective.
