Fix typo setting ingredient rotKind default value to the opposite of what it should be
Fix naija not moving properly on machines with very high FPS.

This bug occured when standing still and attempting to move,
having high FPS and very low difftime.
With near-zero vel, it was not built up enough per frame,
therefore velLen was always < 2 and was subsequently reset back to 0,
which resulted in naija never actually moving.
This bug could be reproduced by holding Shift+F with 60 FPS, and then
holding an arrow key.

Thanks to `Nax for reporting the problem.

(Cleaned out some cruft too, the actual change is the last line of the diff)
