Preserve symbolic links when browsing tracks

So does this only happen when you import them again? Because in my setup those filepaths are correct.

It happens when you import a track that is already in your library (and contains a symlink in its path) again by selecting and opening it through the browse view. Even of you open those files with the same symlink path duplicate entries with the canonical path are created in the library.

Example: Use a symlink for your collection folder.

Oh sorry, I messed around with git and this got accidentally merged, without using GitHub.

However I have tested It and it works for me. It is a good band aid for the common case you have a symlink to your external hard drive in your Music folder.
If you pick such a track by browse, you have now duplicate.

The other direction of this bug is still open. If you brows to your external harddrive, Mixxx will add a duplicate because it is not aware that the track is already in the library via the symlink url.

This LGTM.

Thank you Uwe.
