Changes "no_season" regex to support XofX naming

Previous version would allow for:

Britannia The Great Elizabethan Journey - 1 of 3 (19th May 2012) [HDTV 720p (x264)]

But disallow (because of no spaces around "of"):

Britannia The Great Elizabethan Journey - 1of3 (19th May 2012) [HDTV 720p (x264)]

Also previous extra_info changes from:
of 3 (19th May 2012) [HDTV 720p (x264)]

To:
(19th May 2012) [HDTV 720p (x264)]
