Replace missing .mid files with silence

Browse Source 
This fixes a crash: missing playlist due to missing .mid,
and retains regions for missing MIDI files.

As opposed to missing Audio, we cannot use a SilentFileSource,
because MIDI files are destructive.

This also adds an API to query missing files that have been replaced
with silence to report them to the user.
