Third time is a charm. Fixed a bunch of map things and reverted the axe back to it's premerge values. Also added airlocks back to mining.

Fix to issue #2371

Increased the simple_animal/hostile/move_to_delay, which seems to be an entirely separate value for speed. This code is so messed up.
Fixed problem where hostile animals would attack even the dead.
Players have to wait 5 minutes between dying as a mouse and respawning as a mouse. Global variable mouse_respawn_time determines the respawn time in minutes.

Mice can no longer open airlocks.

Mice can no longer strip items from humans

Mice can no longer put other creatures into disposal units (though they can still climb into disposal units)

Message for when mice crawl into vents removed. Mouse nibbling message only displayed to observers half the time.
Some uses of ismouse() replaced with isanimal()

world.time used to calculate mouse spawn timer.

Spawn timer now applies to being killed via splat().

Fixed derp in surgery step.
Forgot they all instanced at init, not on demand.
Added var/small to mobs, which currently only handles if they can open airlocks. This replaces the use of ismouse().
