Kart-port bugfixes (round 1)

See merge request STJr/SRB2Internal!371

Fix condition which was MEANT to allow attacking Fangboss from the side while bouncing, but instead made it extremely difficult to pull off.

(resolves #248)

Also, since I'm less paranoid now - readd the skin number to its print.

On the recommendation of Sryder, revert everything relating to the `cpusleep` changes except for the new default value of 1.

Mixed declaration + out-of-bounds GCC error fixes for OpenMPT fixes (can't believe I didn't catch the former earlier)

* Default to 1, which means potential for a 1-frame loss every once in a while but no longer a complete cpu hog
* New minimum is 0, since -1 just did the exact same thing as 0 except slightly more optimized.
