Missing Info | Fixes: Rating, Poster, Episode(Date, Thumb) | Clean Up

Missing Info Added:
Show: Original Name, Tagline, Set & Genre
Episode: Rating, Director & Writers

Show Rating:
Works also for comma instead of dot & generally works (plex didn't read it because it wasn't float)

Season Poster:
Can read from Season/folder.jpg (used by DLNA & media browsers)

Episode Date:
Works with 'aired' instead of 'releasedate' (xbmc nfo has aired on episodes)

Episode Thumb:
Can read it for episode_name.jpg (used by DLNA & media browsers)

Clean Up:
indent: comment format because it gave critical
runtime: eduration = eduration_min = eduration_ms = 0 (to be able to log the rest, because it gave critical)
episode thumb: names instead of paths given to episode.thumbs[thumbFilename]
poster & thumb: 'elif' instead of just 'if' (no reason to go further if found)
