ImportTracks
ImportTracks imports up to maxImportBatch tracks in one transaction, so the realms load once for the batch instead of once per track. batch holds one track per line ("\n"), ImportTrack's 12 arguments separated by tabs ("\t"; neither can appear in a valid field). All or nothing: a bad track panics the whole transaction (a malformed line is named before anything is written). It returns the id of the last track. Admin only, as ImportTrack.
