Remove remaining arbitrary restrictions on has_fine_manip

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.
