Fix for the dauvergne_protocol auto-analysis required by the recent changes to the minimise user function.

Eliminated the 'wiz_combo_default' user function arg arg.

This argument is duplicative of the 'default' argument.

The default value of the user function args is now set in the wizard page elements.

This is for the auto-generated user functions.

Fix for the auto-generated minimise user function - the max_iter argument was a mess!

Fix for the auto-generated palmer.create user function - the spin ID arg can be None.

Converted the calc, grid_search and minimise user functions to the auto-generation design.

The minimise user function required a lot of work, as the minimise(*args, *kargs) construct is
incompatible with the auto-generation design. As this is hardly used in the field, everything has
been converted to specific keyword arguments. This will have a side benefit of being easier to
understand for a user. The back end was modified accordingly.

The 'additional' sections are now shown before the 'examples' section in the prompt help system.

The user functions without a base class are now supported in the prompt, script, and GUI modes.

This is for the auto-generated user functions not stored in a user function class object.

Fix for the Uf_info.add_uf() method - the re.search() call was matching '.' to all characters!

The 'num_or_num_list' and 'num_or_num_tuple' argument types are now supported in the GUI.

These are for the auto-generated GUI user functions. The 'num_or_num_tuple' argument type is used
for the diffusion_tensor.init user function, for example.
