playlist: Rework playlist modified detection and dirplay

The modified state is now an explicit flag that has to be
set whenever a user-triggered modification occurs. This is
recorded in the control file to ensure it doesn't get lost
after resume. There may be some places I missed where the
modified flag should be set/cleared, but it seems to work
well enough right now.
