This makes writing tests much easier. This also simplifies the campcaster-import
script.
Changed BasicStor::bsSetMetadataBatch() to do one query for all values instead
of one query for each value to update. This speeds up campcaster-import by about
10%.

Adding playlists is not supported yet.
Added Scheduler.php class.
Added unit tests for Scheduler.
Updated install & upgrade file with new table structure.
Removed a lot of old defunct unit test stuff from storageServer /var/tests dir.
