Piano: Move piano roll internals to AudioEngine

Browse source 
The piano roll data definitely belongs in AudioEngine along with the
note and time data. Now RollWidget only has GUI information, much like
the other widgets.

Note that this commit exacerbates issue #1158 which is caused by
RollWidget::paint_event().
