This pr makes xenomorphs less awful via some additions and porting some fixes:
-removes the NO_MINOR_CUT that is not used anywhere and replace with NO_EMBED that stops things from embedding into mobs, like xenomorphs, shadow people and golems
-adds the night vision verbs to xenomorphs
-fixes aliens eggs layers behind under their weeds
-fixes some hud things missing
-makes their limbs unbreakable
This should make them a bit less buggy.
