Fixed evidence bags so the items inside are now visible even when the bag is inhand (the problem was that overlays += obj uses the object's layer variable rather than the default FLOAT_LAYER. So the hud was appearing over the overlays. Fixed it by using image(obj) to take a snapshot). Changed the overlays to underlays to make them look better. Fixed issue 637 where putting objects in bags which were currently in your inventory did not remove the item from your inventory.

Replaced the obj variable var/see_face. It was used to determine whether something (namely masks/hats) hid your identity. Replaced with the HIDEFACE bitflag for var/flags_inv variable. Moved the var/flags_inv variable from atom/ to obj/item/ as only /obj/item/ can be in your inventory in the first place.

Fixed get_visible_name() so it takes into account any item on the var/head when deciding if your face is obscured. (While I'm at it, just dump a comment here if there's anything that should hide your face which doesn't and I'll add the flag.)

Removed the var/alien_egg_flag variable from mob/living/carbon/ and replaced it with the XENO_HOST bitflag for var/status_flags variable. You can now suicide whilst impregnated with a xeno (since you will chestburst even after death, that restriction is no longer necessary).

Any mob/living descendent can ghost even when not dead. However, ghosting whilst not dead results in the ghost eing unable to return to it's body for the remainder of the round. (It has a warning popup)

The suicide verb can only be used by humans when they can move and are not cuffed. These verbs will be totally replaced very soon with the 'fun' IC suicides I'm working on. Suicide is largely redundant given that anybody can ghost now, just didn't want to jump the gun in removing it.

Known Issues:
We've got var/flags_inv, var/slot_flags which could possibly be merged as they both deal with obj/items, although I'm not sure if we can fit oth into the 16-bit limit. Just something to look into.
There are bitflags GLASSESCOVERSEYES, MASKCOVERSEYES, HEADCOVERSEYES, MASKCOVERSMOUTH, HEADCOVERSMOUTH in the var/flags variable which should really be merged with or moved alongside the very similar flags in var/flags_inv. Comments next to the defines suggest as much.
You can borg dead/clientless brains but can't remove the brain fromt he borg once you realise it's a dud. >.<
