William McPherson ebaadda6bd Piano: Make note() callable by multiple sources
Rather than checking key codes and mouse positions, we should have a
more general way to play notes. You can call note() either with a
KeyCode or a PianoKey directly.

Additionally, m_note_on[] is now an array of integers instead of bools.
This allows multiple sources to play a note. This is kind of like a
"reference counted note": two sources can increment the note and it will
only turn off once they have both decremented it back to 0.

We are now only using keys[] to prevent multiple consecutive calls to
keydown_event() (when a key is held), since that would result in playing
a note many times.
