Implement ArchiveBrowser filtering

Filter ArchiveBrowser by Quality and/or size:
* Quality: only show series with a quality less or equal
* Size: only show series still fitting onto the DVD
* Both: only show series with a quality less or equal _and_ still
fitting on the DVD

Use QItemSelection instead of going through the selected items in the
tree. Seems to work somehow...
