filechooserentry: Use a GtkFileFilter for filtering

Browse Source 
That way, we can use the regular filtering features of the
filesystemmodel instead of having our own filtering function that
duplicates much of the matching code.

This also removes the broken-on-windows feature where files strting with
a dot were not autocompleted.
