Added some checks to the dauvergne_protocol GUI test for the maximum number of iterations.

These tests will currently fail, as the number of iterations are far to high and do not match the
equivalent system test.

Fix for a bug introduced in the previous revision (r14761) in the intensity_generic() fn.

This generic peak list reading function needed to return 5 element lists rather than the original
4.

Bug fix for the reporting of non-matching lines in the spectrum.read_intensities user function.

The file data printed did not match the actual intensity data currently being processed, hence the
wrong data was being printed as non-matching.

The spectrum ID is no longer stored if spectrum.read_intensities fails to load any data.

A call to the delete() function has been added to remove all data loading prior to the error.

Redesigned the gui_raise() function so that it is more user friendly.

The relax controller window with error message is shown first, followed by the modal RelaxError
message dialog on top of all other windows.

The spectrum.read_intensities user function now throws a RelaxError if no data was loaded.

This is to tell the user that something went wrong, and makes more sense in the GUI mode.

Another attempt at handling the pipe editor window updates.

This fixes the test suite test_load_state_no_gui() GUI test. The pipe window update needs to have
all pending wx events flushed so that the pipe window is up to date before emulating a pop up menu.

Fix for running the test suite in debugging mode.

The self.capt StringIO structure is always necessary for the final print out.

Fix for the results viewer window on MS Windows - it is no longer hidden after switching pipes.

For some reason MS Windows always brings the main GUI window to the front when pipe switches occur
(probably the notebook switching).

Bug fixes for racing in the results viewer window on MS Windows.

wx.CallAfter() calls are required for this to work on MS Windows.
