* src/modest-ui-actions.[ch]:
        * Refactored and reworked fullscreen methods to use the
          new modest_window_mgr methods.
        * New Zoom plus and Zoom minus action handlers using the new
          ModestWindow zooming interfaces.
        * Added handlers for toggle actions "Show Cc:" and "Show Bcc:".

        * Implement the ModestWindow set_zoom and get_zoom interfaces.
          Added menu actions for switching among different zoom levels.
        * Implement full view scroll of the editor. Now it includes
          the headers in the scrollable area. It uses the mark_set
          event handler of the body GtkTextView, to update the scroll
          current value.
        * Replaced buttons and labels form header fields with
          HildonCaption, to fit UI specs (and make the UI more usable).
        * Added autocap setters.

        * Support for fullscreen modes (not ended yet).

          the selected menu option.
