Version 1.15 Released! Custom Music Fixes

Version 1.15 lands, with some fixes to the custom music in the music options, and some minor fixes.

- Small arrows have been added in the title screen to show other options are available other than "press start"

- The "achievement" text in the title screen now flashes like the other options.
- The Bubble Shield and the Fire Shield are no longer have their animation frozen when the player is on the ground during the snowboard sequence in Diamond Dust Zone 1

Special thanks to IngaRasen for reporting the following bugs:
- Fixed a bug that prevented custom music from looping in the Music Options Menu
- Fixed a bug that set back to MD option the wrong tracks. The code was supposed to reset to MD those that were set on CUSTOM but removed from the LoopInfo file at a later time.

Special thanks to Nakkurusu for reporting the following bugs:
- Fixed a bug that temporarily froze tails if the player is hurt and accidentally grabbed by tails. Tails wasn't supposed to grab the player in the first place...the check is no longer tied to the hurt flag, but to the hurt animation instead.
