v1.33 Update

A quick update addressing some Wii U issues regarding the WHUB version.

• [Wii U] Fixed the home menu icon
• [Wii U] Hid the RPX version from the system menu in Aroma (now only WHUB shows)
• [Wii U] Removed the Quit button from the WHUB build so you can now only quit from the Home button
  • Quitting from in-game previously caused a softlock in Aroma; the RPX (Homebrew Launcher) build still has this option
  • For the same reason, also reworked the "Exit Game and Apply Changes" button on the WHUB build into a "Save Changes (Restart To Apply)" button
• [Wii U] Pressing L/R to change music no longer immediately saves the music index
  • SDL2 counts the home button menu's "Close Software" button as an L button press for some reason, so quitting with this method would also change+save the song index; removing the save fixes this

Only the Wii U version has been updated; other versions are unchanged.

Enjoy!
