Conflict in filenames when adding to queue

if filename.contains(path) {

In the above line, when you try to add a new song to the queue, it iterates over the song_filename list and see if it contains the partial filename from the chosen path.
In theory there could be multiple songs with the same filename, that would lead to addition of multiple different songs of the same filenames in the queue.

The better solution would be to determine the absolute filepath relative to the db when we handle_enter using 'self.browser.path'
