echel0n ee458bd211 Fixed AttributeError: 'NoneType' object has no attribute 'is_scene' in scene_numbering code.
Show root dirs can not be set from general config menu.
Mass editing shows now has the ability to delete root dirs as well as edit them.
Daily search no longer is restricted to just 1 week of results for searching from which now allows for replacing lower quality downloads with higher quality ones if available.
RSS Cache is updated for each provider on demand now when performing manual, failed, backlog, or daily searches.
