Chambering, Velocity Pinch, TestPawn

Both done.

Chambering:
+ Hold rightclick to chamber. Your next attack is queued right when
current attack ends. Therefore you can run zigzag, but only at the very
end does your direction matter

Velocity Pinch
+ Pretty basic one right now and affects all stances with same modifier.
TestPawns are also affected

TestPawn
+ Velocity Pinch
- GroundSpeed limiter removed. Same speed as player
