Removed Year from EpisodeParseResult (we never used it anyways).

Episode parsing REGEX will properly handle filenames with S01E01/1x01 naming.
Added REGEX to support seasons with more than 100 episodes (0-99)... Stupid soaps.
Title Normalizing REGEX will keep the year (has to start with 19 or 20 and be exactly 4 digits long)
