[mythtv] Heads up: Smart playlists in MythMusic

I hadn't seen mention of your work so I had no idea it was in progress.
Regarding the format, I only opted not to embed a SQL statement so that
whatever frontend didn't need to "know" the SQL necessary so that if
something did change in the database, only the parser had to be modified
(not both the graphical and/or web frontends). Plus, it's probably just me,
but embedding SQL just rubs me the wrong way. By parsing I can double check
the inputs from the frontends to be sure things are valid.
I imagined exactly the type of frontend you mention as iTunes does with
any/all and then a series of statements. I just hadn't gotten to the
frontend part yet and wanted to get at least the backend support in place so
people could use it.
If I've stepped on any toes here with this WIP, let me know, I'll be happy
to let it go.
