Monkey and aliens now all use carbon/examine().

Fixes monkeys being able to strip and uncuff people while handcuffed themselves.
Add an inhand sprite for facehuggers (taken from Xhuis) (but they don't appear for large queens, it'd look ugly).
Xenos now regenerate plasma on alien weed even when injured but at half the normal rate.
Moved queen/large/update_icons() to humanoid/update_icons.dm
