S3 Sonic v1.2

Changelog:

1. The spindash is now as strong as it was in the Genesis games
2. Added Game Over and Drowning as part of the S3 Music affected list
3. Roll angle should now be fixed and not slightly tilted
4. Being how clunky 2D mode is, the momentum-preservation aspect of the mod gets disabled

Changelog:

1. Springs should now hopefully be more consistent
2. Rewritten music code
3. 1-up and Level Results screen songs are now affected by the S3 Music option.
4. Super Sonic's standing sprite is fixed
5. Fixed Sonic's Continue Icon offsets (alongside a single stray pixel deleted)
6. Fixed an warning that pops up from time to time
7. Fixed Sonic's spindash and kick power that get affected by his scale
8. Added new option, "S3 Slope Angle" that makes Sonic's rotation affected by the current slope he's standing on.
9. Spindashing shouldn't (hopefully) be as broken now

Remember that S3 Sonic's v1 options won't carry over to v1.1 so make sure to edit them again.
