Taking care of a few more issues. Mainly, super slow animations when running at insane framerates, and muted sounds.

Changelist

• Reworked frame sync logic, again, to fix slow animations. Tries 60fps vsync first, then CPU sync.
  
• Fixed bad language selection dialog when booted with unknown language
  
• Fixed zeroed sound volumes on locales with "," decimal point
  
• Always stretch screen to extents in windowed mode
  
• Added 720p and 1080p commandline options to override native fullscreen resolution
