Piano: Use LibDSP::Keyboard for all keyboard-playing logic

Browse source 
The only major functional change is that the Track now needs to know
whether it's active or not, in order to listen to the keyboard (or not).

There are some bugs exposed/created by this, mainly:
* KeysWidget sometimes shows phantom notes. Those do not actually exist
  as far as debugging has revealed and do not play in the synth.
* The keyboard can lock up Piano when rapidly pressing keys. This
  appears to be a HashMap bug; I invested significant time in bugfixing
  but got nowhere.
