Title: Multi dot extensions dev

Renaming files with multi dot extensions are not renamed
Postprocessing files with multi dot extensions are ignored.

Multidot extensions like
PS3 epsiode thumbnails: .avi.cover.jpg
or multiple subtitle files: .en.srt .nl.srt

Normally determine extension by finding first dot (.) approaching from right.
For associated files use length of media_file basename to determine the extension (approach from left).
