Make the file path in the "Song Info" window selectable text
When wanting to add tags to a song, one might go in the Song Info dialog and naturally want to copy title and artist from the file path on the left and paste them in the corresponding fields on the right.
It is possible to right click on the file path and copy it, but the path is URL-encoded (at least on Linux), making any non-ASCII character be unreadable and it is impossible to copy only a part of the path this way.
Please disregard the second sentence of this bug report. I am using the Qt interface. I am talking about selecting the artist on the left, pressing Ctrl+C, and then doing Ctrl+V in the Artist field on the right, see screenshot.
