All the wizard method 'event' args have been converted to keyword args.

This is for better remote control, for example by the GUI tests.

All the model-free GUI auto-analysis method 'event' args have been converted to keyword args.

This is for better remote control, for example by the GUI tests.

Import fixes for the spin viewer window.

Fixes to the model-free GUI auto-analysis test.

This includes an attempt to test out the spin viewer window code paths, thought that was stopped
short due to a bug in the spin viewer.

Converted many GUI functions expecting a wx.Event to have the event as an optional arg.

These are now keyword args defaulting to None. This allows remote control of GUI elements, which is
needed for the GUI tests.

Bug fix for the graphics.fetch_icon() method.

This was not returning the full path, just the relative path. This results in the failure to find
and load the icons when relax is run from any directory other than the installed directory.

Bug fix for the calling of the GUI user function objects.

The user function page update_args() method is now being called to update all the ComboBoxes with
the current relax data store data. Without this, the lists would be empty or out of date. A call
requiring a user function arg to be set on a read only ComboBox would then fail.

Bug fix for the Value GUI input element for the SetValue() method.

When None was being supplied, this method did nothing. This behaviour is incorrect! It should
instead blank the GUI element!

Removed the reinitialisation of the relax data store GUI object in the GUI test tearDown() method.

This is not needed as it is done by the data store reset anyway.

Removed a time.sleep() call which slows down the GUI tests by a significant amount.

This adds 0.5 seconds per user function which display info. For example this is 8 seconds for just
the Bmrb GUI tests! This delay is not necessary, so has been eliminated.
