Project Filelist for Windows Privacy Tray

Another bug fix release.

* Bug fix in file name handling for the MAPI feature.
                                                                                
* The key sign dialog now lists all user IDs and not only
  the primary to indicate that all user IDs will be signed.
                                                                                
* The signature property dialog now contain all useful
  information about the sig, which includes the creation date.
                                                                                
* A bug in the key deleting code has been fixed. The problem
  is only related to the GUI synchronisation and not the delete
  process itself.
                                                                                
* Support to retrieve the PKA record directly from the DNS.
  This allows to perform a validity check of the key if a
  PKA record is available for the key.
                                                                                
* The Current Window Support does know correctly reset the
  cursor position within the foreground window.
                                                                                
* Fix problem in the key cache which might lead to a segv
  after importing a secret key or if the last secret key
