The testing of the various GUI windows for race conditions now occurs in the NOE GUI test.

This should significantly speed up the model-free auto-analysis GUI test.

Bug fixes for the GUI tests on MS Windows.

The GUI interpreter thread is now flushed prior to the peak list wizards, as the wizard's user
functions are synchronous (and the previous ones were asynchronous).

Bug fix for the scons clean target on MS Windows.

The build and dist directories from the Mac OS X py2app program are now only deleted by the
clean_all target which checks for the paths.

Bug fix for a race condition on MS Windows blocking the test suite.

The analyses update_spin_count() call sets the value of the spin systems GUI element. This is now
via a wx.CallAfter() call to prevent the race in the GUI.

Attempt to fix the infinite running of the test suite on MS Windows due to the flush() implementation.

The GUI interpreter thread's queue object task_done() method is now called to properly clear the queue.

Added the 'Go to top' and 'Go to end' entries for the relax controller pop up menu.

This includes the appropriate oxygen icons.

Fix for a bug introduced at r14703.

The page changing and page changed events are now handled separately. This allows the page changing
to be blocked while fixing the MS Windows bug of page changing happening after the
wx.EVT_NOTEBOOK_PAGE_CHANGED event.

Bug fix for MS Windows - the user function menus are now fully deactivated during execution lock.

The submenus were strangely not all being deactivated, so now all submenu items are also
deactivated.

Bug fix for the switching between analysis tabs on MS Windows.

The tab had not been changed when on_page_change() was being called (in contrast to GNU/Linux and
Mac OS X). Now wx.EVT_NOTEBOOK_PAGE_CHANGED is being used to bind the page change event rather than
wx.EVT_NOTEBOOK_PAGE_CHANGING.

The peak list and relaxation data GUI element pop up menus are now disabled with the execution lock.

This will prevent weird bugs.
