[dev] Fix for sorting in IMP searchs

[Sebastián Calero]

With this little fix, the sorting of search results works:
 
Index: Search.php
===================================================================
RCS file: /framework/IMAP/IMAP/Search.php,v
retrieving revision 1.1
diff -r1.1 Search.php

<             $indices_sort = @imap_sort($imap, $sortby, $sortdir, SE_UID);
---
>             $indices_sort = @imap_sort($imap, $criteria, $dir, SE_UID);
 
 
Greetings.
