Merge remote-tracking branch 'froggestspirit/master' into master

Brought the visualizer back to the main screen.

Didn't include the amplified volume read on channel 3.

Conflicts:
	misc/musicplayer.asm
Music Player: Don't reset visualizer state when switching modes.
Remove globals.asm from the repository.

This used to be a generated file, and was committed by mistake.
Music player: Start can back out of zen mode.
