Cleaned up more of the XEM scene numbering code, integrated it better into sickbeard so that season and episode info from XEM is passed in right away when a search is performed instead of where it passed in last minute which made things harder to code around. All provider options now should be fully in sync with XEM searches.

Fixed a issue with TVRage returning scene numbered data which didn't agree with how TheTVDB database is setup so now we convert the data back so TheTVDB will accept the data from TVRage on certain shows it was not.

Minor bugfixes here and there.
