Remove touching pattern as mute - only mute in mute-mode.

[tuj]

Remove the instant muting when selecting a part by touching it. Instead only mute a part when mute mode (red/green) is enabled.

+1 on this. This is another reason I'm still running on old firmware.

+1 The touchscreen is one of the great immediate things about the module, so it would be nice to have control over when the pads respond as mutes. Thanks!
