[GoogleCodeExporter]

Enhancement request lodged as per ltfearme so that he can get this enhancement 
into the last release.

Add additional option to New Episode Indicator*

- None
- Unwatched Episodes
- Recently Added Episodes
- Recently Added Unwatched Episodes*

Reasoning:

Episodes that are recently added are marked new, however after watching those 
new episodes, it would be good if they were no longer marked as new in the GUI.
