Currently the match status of a release only exists as a text string that is appended after the release title like `Albumname (11/12; 1?; 2*)`

This single status field should preferably be split into at least:

• a correct matched percentage (ie 11/12 = 92%)
• number of unknown/extra files (ie 1)
• number of duplicate files

It should then also be possible to filter and/or sort on these status columns
