Add an option to cancel the filter popup


At GTK client is possible after open filter popup window, click the icon filter again and close the current popup and not to do RPC search to server.

In SAO after open filter popup window can’t close popup window and close de filter popup


Add inside modal-title in modal-header popup filter close button.

        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>

Why not adding a cancel button near the find button like we do on most wizards?

Indeed I think it is the behavior of the desktop client that is not right (but it is not a big deal). The input of the search box should always synchronized with the actual search.
