Update to 3.13.1:

2015-04-20 meld 3.13.1
======================

  Features:

   * Previously, Meld could show very different results in file vs. folder
     comparisons when the files differed in line endings. These are now much
     more consistent.

      * In folder comparisons, applying filters now also normalises line
        endings (Kai Willadsen)
      * In a file comparison, if the files-are-identical notification is shown
        when files differ in line endings, this now mentioned (Kai Willadsen)
      * There is a new preferences controlling whether to apply text filters
        during folder comparisons, defaulting to on, which also controls line
        ending normalisation (Kai Willadsen)
      * Help documentation has been updated with details of how text filters
        are applied in folder comparison (Kai Willadsen)

   * Folder comparisons will now show an identical notification similar to the
     one used in file comparison (Kai Willadsen)
   * The "New blank comparion" button now works for folder comparisons \ 
as well
     as file ones (Kai Willadsen)
   * In folder comparisons, the expansion state of the tree is now remembered
     when you collapse and re-expand a row (Kai Willadsen)

   * Install fixes (oco)
   * Code style fixes (Sandro Bonazzola)

     stable Meld (Kai Willadsen)

     URIs (Kai Willadsen)
