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
to search for show in cache.
^(?:[0-9]+)?(?:\[(?:.+?)\][ ._-])?(?P<series_name>(UEFA|MLB|ESPN|WWE|MMA|UFC|TNA|EPL|NASCAR|NBA|NFL|NHL|NRL|PGA|SUPER LEAGUE|FORMULA|FIFA|NETBALL|MOTOGP)?.*?)(?:[ ._-]+)(?:(?:[sS][0-9]{1,2}|[eE][0-9]{1,2}?|(?:Season|Part)|(?:[0-9][x][0-9]{1,2}?[x ._-])|(?:[0-9]{1,3}[ ._-])|(?:[0-9]{4}.[0-9]{2}.[0-9]{2})|(?:[0-9]{2,3}[^0-9])))

This Regex will match Doctor Who 2005 now as well as returning a second un-named match for the sport if it is available.
