The incremental collection scanner, in conjunction with the AFT code, now causes the CollectionDB::fileDeleted() signal to be emitted when it detects files that were removed but not moved. This functionality was added to make it easier to add AFT support to the Moodbar; also, Jeff may use it in the Playlist. The API may change a bit when I actually write thef AFT+moodbar code, so don't use it before then.
