Option to automatically pause practice session when metronome is off

Add an option to sync up practice session timer with metronome on/off status. With this option enabled the timer will automatically pause when the metronome is off and resume as soon as it's back on again. This way distractions and pauses won't count as practice time, only the active metronome usage will (if the entirety of one's practice calls for a metronome). That helps self discipline ang gives a cleaner sense of achievement.

Interesting idea - but don't you also do legit practice without a metronome which should also count?
