PEP8 Fixes
Add SD `web-dl` support.
Fixes detection of things like `Project.Runway.All.Stars.S03E02.Bitten.By.The.Fashion.Bug.WEB-DL.x264-RKSTR`
`Cutthroat.Kitchen.S01E03.Tac-o.the.Town.WEB-DL.x264-JIVE`
This will pick up mSD's 480 web-dl encodes now. So people may want to add ignore_word for `480p` to stop those.
Added `480p` to ignore_words to prevent mSD re-encodes.
