NameParser fix to only process shows that SickRage knows about.

Created a RegEx to provide show name from file name for get_show_by_name

This matches sports as well:

^(?:(UEFA|MLB|ESPN|WWE|MMA|UFC|TNA|EPL|NASCAR|NBA|NFL|NHL|NRL|PGA|SUPER LEAGUE|FORMULA|FIFA|NETBALL|MOTOG(P)))?(?:[0-9]+)?(?:\[(?:.+?)\][ ._-])?(?P<series_name>.*?)(?:[ ._-])+?(?:Season|Part)?(?:.[eE][0-9][0-9]?)?(?:.?[sS]?[0-9][0-9]?)
