First set of changes to add 'genre' to Track
Merge branch 'master' into add-genre

Conflicts:
	src/com/pugh/sockso/music/Track.java
Forgot some stuff & bad merge
Added genre to data model and API.

Still need to update web page features & probably some javascript
Ensure track info updates for new genre field when re-scanned
Added a genres table instead of just an attribute on tracks table
Allow run, debug, profile targets to accept all cmd line options

These should be set from the sockso.properties file via run.arg.<option> properties
