Bug#425806: searching should ignore diacritics

[Thomas Bushnell BSG]

Package: rhythmbox
Version: 0.10.0-3
Severity: normal

--- Please enter the report below this line. ---

Just as searching should ignore case, it should also ignore diacritics.

Create, for example, a track with the artist as "Arvo Pärt" and then search for "part". Notice that
the search fails to match.  Notice that a search for "pärt" will succeed.

This is actually a bug, not wishlist, because the unicode standard and common gnome practice
call for searching in the ignore-diacritics way just as for ignore-case.
