This happens for not syncing before working -__-

- Again appears the fix to the crash in SSMaster
- Again appears the PlayStartSound fix when entering PlayerOptions...

- For some reason, the support for the separate announcer intro for
ScreenSelectCourse had been removed. Restored it.
- Added support to define a custom font for the difficulty meter in each
course entry, instead of forcing to use "Common normal". A redir might
be needed for compatibility with other themes.
- Removed an assert that causes a crash in Oni mode. Did it just for
compatibility with DDR themes, I hadn't seen any side effects of this.
- Added the possibility of using separate "Game Over" images in
ScreenGameplay when playing in Oni mode (like it happens in DDR games),
conveniently named "ScreenGameplay Oni Gameover P1/P2". If the file
doesn't exist, the game will look for "ScreenGameplay oni gameover"
