update: collating all episodes into one big list

as I proposed in the xbmchub forums, the change collates all episodes of the series into one big list so you don't need to choose "More..." over and over again. I've tested the change on my XBMC setup, I hope I managed to copy it here correctly.

P.S. my first time using GitHub.
P.S.2 my first week using python ever.
