This commit adds baystation's rigsuit system on top of our own hardsuits;
Our own hardsuits still function fine and are around, but these are
available to admins. Next commit will contain balancing and player
implementation stuff.
This commit removes all (most) of the remaining code limiting xenomorphs
that have has_fine_manipulation on an entirely arbitrary basis. Xenomorphs
with has_fine_manipulation may now interact with NanoUI, and will only
break computers on non-help intent. The can also tear down walls, since
walls used an ishuman check in place of an isAdvancedToolUser check as
they should have.
Minor refactor to machinery.dm as well; Instead of the slightly
(completely) insane attack_hand restriction to humans and silicons (it was
a multi-line IF, why), it now checks user.IsAdvancedToolUser(); This means
restrictions on monkies will actually function properly now.
