Add option to show note values on notes in Piano Roll (#4466)

Browse Source 
Add the option to show note values on notes in the Piano Roll. This
functionality is currently coupled with the option "Enable note labels
in piano roll" which can be found in the main menu.

The notes are rendered at about 80% of the notes height. They are only
rendered if they fit on the whole note and if the font does not become
too tiny.

Enable the configuration of the note value text's color via the
stylesheets and set the value to white for both shipped themes.

Other changes:
* Clean up some warnings about old school casts and implicit casts.
