More discreet shells (#2272)

changes:

Shells Frames' species no longer show up on examine. They can still be detected via. other means such as checking pulse, health scanners, or them being damaged.
IPC Tags are now located in the head instead of the groin.
Note: This does not affect tags showing up on examine. They must be manually removed from the shell to completely disguise their examine text.
