MediaGroup: Title sanitization common length
With the current integration of MediaGroup, it seems that the title isn't grouped by the most common pattern as it used to be for VideoGroups.
- a_cool_filename_01.mp4 - a_cool_filename_02.mp4 - a_cool_filename_03.mp4
The above files will be grouped into a MediaGroup named:
a_cool and not
a_cool_filename_0 as it used to be.
