commit 523864bd8dc0d928b549a59fe6cf6ccde66953b1
branch master

    Modifiy attachment save function.

      Allow to supply a defaultFileName for saveAttachment that is
      independend ot the Url and will be preselected in the FileDialog.
      Also check if the MimeType of the attachment can be determined and
      if so use the patterns of this mimetype as a filter so that the
      file Suffix is correctly set.
      CCBUG: 257790
