Shifted the combo_list GUI element into the gui.input_elements package.

Fix for the Sequence_2D GUI element for when the first dimension is variable but the second is fixed.

This allows the bmrb.citation GUI user function 'authors' argument element to be functional.

Another missing import, accidentally deleted.

Reintroduced some accidentally deleted imports.

Fix for the table in the spectrum.error_analysis user function description.

There was a lot of whitespace in front of the first element of the table!

Fix for the GUI test execute_uf() method - the user function page is now updated prior to execution.

This call to the user function page on_display() method allows the read only ComboBoxes to be filled
with the allowed values. The subsequent SetValue() call will then choose the element from the list,
rather than having the element left to the value of None.

The NOE auto-analysis GUI test has been converted to the new auto-generated user function design.

The NOE auto-analysis peak loading wizard has been converted to the new auto-generated uf design.

The prompt-based interpreter no longer sets the status.prompt_intro flag in the __init__() method.

This flag is now set by the instantiation of the singleton status object. This prevents multiple
calls to the Interpreter.__init__() method overwriting this flag. This fixes problems in the GUI
tests.

The GUI user function on_execute() method no longer shows the controller in test suite mode.

The controller Raise() method was being called at the end of the method, without checking
status.show_gui!!!
