Removed the leading whitespace from the colour module documentation variables.

All leading whitespace is stripped from the docs before creating the auto-generated uf description.

The detection of the end of the table has also been simplified, as stripping the whitespace broke
the logic.

Fix for the Molmol wizard graphic paths.

Fix for the auto-generated GUI user function descriptions.

The additional documentation was not passing through the process_doc() method, and hence was not
being formatted for the wx.Text element. This was making the tables look very ugly!

Fix for the Selector_dir class - the default of None needs to be converted to wx.EmptyString early.

This was causing TypeErrors in the wizard pages.

The simple Value wizard page element default for an integer is now a wx.SpinCtrl.

If the element_type arg is set to 'default' and the data type is integer, then a wx.SpinCtrl will be
used.

Whitespace clean up.

The align_tensor.init param_types arg is now a ComboBox with the choices in the GUI.

The generic_fns.grace.get_data_types() function is even more fail proof.

The return_data_desc() call was sometimes raising a RelaxError when not implemented for certain
analyses.

Converted the grace user functions to the auto-generation design.

This required created the generic_fns.grace.get_data_types() function for returning the data type
descriptions and values for the current data pipe. This is to replace the code in the old grace
user function update_parameters() method so that the data type fields are updated according to the
analysis.
