Update OSUtilities.py

"If you define moviehash and moviebytesize, then imdbid and query in same array are ignored."
"If you define query, then moviehash, moviebytesize and imdbid is ignored."

Maybe I don't get it but this seems contradictory. I had another go, trying to get rid of the clutter.

Manual search only uses the manual search string. Movie search first uses moviehash, moviebytesize and imdbid and if no result then uses the query string as a last resort since that is probably what you would enter in a manual search.

This is some tests I made, returned subs on 8 movies searching for english and swedish:
This version: 13, 9, 6, 12, 8, 5, 1, 2
Old version: 13, 9, 6, 434, 8, 5, 7, 143

From what I can see all the excess are for other movies, even with the 2nd from the end, this version returned 1 and the old version returned 7 of which 6 where for other movies.
