Removed entity defined name, replaced with airing_title
Standardized on UTC for time. Shifted incoming times in Telvue parser
Added airing_duration to filter out short shows like PSA's and promos from the schedule display
Added hms_field as a dependency
Moved Airing Type into it's own submodule
the cm_airing_type module had lots of code that was copied and pasted in from cm_airing, so i've removed a lot of that, updated function names, and made the cm_airing_type.info file actually reflect reality.
