Add a ranked full text search view

[Daniel Schürmann]

As discussed in Bug #689291 and https://github.com/mixxxdj/mixxx/pull/256 it would be nice to have a special view with a ranked fuzzy search, that allowed to find track even if it is misspelled.

The current search box just filters the current view. The best match may located somewhere in the list , because the original sorting is reserved.

Related feature request: Less specific unicode search

(originally posted on http://www.mixxx.org/forums/viewtopic.php?f=1&t=8751)

Example:
If we take the album of the artist "Manolín 'El Médico de la Salsa", I wish to be able to find it if I search "Manolin El Medico de la Salsa"

In general, I wish that the search will be a little more relaxed and treat similar Unicode characters (spanish and english for my use case) as the same.
