Revise conditions under which players use spinheight and enter gaps:

- players with SF_NOJUMPDAMAGE but *not* SF_NOJUMPSPIN now always use spinheight while jumping (i.e. even with PF_NOJUMPDAMAGE), as long as their panim is PA_JUMP or PA_ROLL
- players with SF_NOJUMPSPIN no longer use spinheight while jumping (but,)
- PA_ROLL is now an acceptable condition for using spinheight (but not for entering gaps, e.g. S3K shields will shrink the hitbox but not allow gap entry on their own)
- flying players now only use spinheight if they do not have SF_NOJUMPSPIN (you're welcome, EggpackRE)
- players with neither SF_NOJUMPSPIN nor SF_NOJUMPDAMAGE use the same conditions as in 2.2.9 prerelease, i.e. use spinheight and can enter gaps unless they have PF_NOJUMPDAMAGE
