Feature request: choose which entry to remove

[fractalic]

This is a feature request for the ability to choose which of the duplicate entries is removed.

This is useful in the following scenario:

1. A playlist is added to Traktor
2. Traktor adds previously un-imported files to its Collection
3. Those same files are moved into Traktor's music source folder
4. Import Music Folders is performed in Traktor, creating duplicates
5. The duplicate file paths are removed with Librarian. The paths removed are the relative paths specified in the playlist.
6. Import Music Folders is performed in Traktor, re-creating duplicates

A workaround is to ensure that files referenced in playlists are always in the Traktor Collection before the playlist is opened.

Another workaround is to ensure that files referenced in a playlist are never added to a folder monitored by Traktor after the playlist is imported.

The ability to choose which duplicate is removed, via Librarian, would be a quicker solution than the workarounds.
