Feature : Filter a path the same way we can filter the database.

[Steve Beaudoin]

I can select one of the filters applied to the database to list only originals, clones, etc.

I would like the same possibility on the paths. This way, I would be able to apply a "clones" filter and delete the items present in the list if I want to keep only the originals.

I suggest that the different filters available now should be moved on top of "mame roms" list as a combo box and the content of the list would be filtered by what is selected there.
