ChangeLog

*0.3.0 ()

    added globally settable key long-press delay
    when using trims, longer beep at value reset and short pause ignoring keys
    momentary trims/keys now sets value only when state of buttons changed

	possible to map momentary and non-momentary keys to the same
	channel/mix value
