Tweaks to output code to ensure output passes youview validation
Catch case where availabilityStartDate field is not populated, and do not create corresponding field in xml
- LoveFilm classes, now with extra camel casing!
- Youview genres are now populated from a .csv mapping from LoveFilm genre to YouView genre
	- as a result, the LoveFilm -> Atlas genre conversion code now lives in atlas-feeds
Refactoring after code review
Merge branch 'mbst-4542-tv-anytime-output' into stage
