musedata2hum work title and movement title

[craigsapp]

For MuseData to Humdrum conversion, the 7th line in the file header (excluding comments) is the title, and the 8th line is the movement title. These should be mapped to !!!OTL and !!!OMV.

Also the 6th line is the (principal) source printed edition, which should perhaps be mapped to !!!SMS: (but this is not typically a full reference, just the publisher and primary editor of the edition, not to a specific edition or reprint of an edition.
