Good to go

Includes some syntax fixes too.  Now to actually get the Threshold
effects together (they'll be one-offs in the iuse, I think.)
Safety-catch

I'll handle the threshold-gaining in a separate PR--it'll likely show up
in the iuse, be a roll that gets easier based on your category strength.
Remove testbed remnant

"MAYBE" was the test trait for prereqs2.  You needed (("CLAWS" ||
"CLAWS_RETRACT") && "PREREQ") to get "MAYBE".

The Threshold trait was UHUH and the test-trait that required it was
NOPE, incidentally.  Dev trivia FTW.
Thresholds and initial post-Thresh mutations

There will be more post-thresh and double-prereqs.  But these ought to
start things off well.
Minor style fixes.
Fix vehicle facing when dragging, thanks to BevapDin for making the same fix in map::rotate().
