Edit: Auto search mode

While the auto search mode is active, Cross tries to find words that fit into the crossword. Two conditions must be met:

While the auto search is running, a progress requester with two progress bars is displayed. The first bar corresponds to the ``limit'' variable, the second one shows the progress of the current search attempt. The auto search mode is finished by clicking on the ``Stop'' gadget, or when no more words can be placed.
