Improved subtitle search that includes release group search

[ripkrizbi]

Hi, this is a great fork!
Would it be possible to somehow include the original release group information in subtitle search process? If the rename file postprocessing is on, then the file gets renamed and this information is no longer in the name itself. And if I understood correctly from the logs, the filename is used as the basis for the subtitle searches. The info on the release group still exists in the SB database, would it make sense that the subtitle search uses this information rather than the filename itself? That way we would not have to choose whether to rename the file or to download the (correct) subtitle but we could have both postprocessing options not mutually interfering :)
Thanks!
