Decapitation Fixes, Head Reattachment Surgery

Added a new surgery- Head reattachment, for the decapitationally challenged. Performed via retractor, fix-o-vein, hemostat, cautery, head. Fixed logs and messages for decapitated brain removal - No longer shows as the head cutting the head open, and no longer shows the debrainee as the debrainer to admins.
