The specific API param list object now sets up a number of spin params and min params.

The spin 'select' and 'fixed' parameters are set up in the __init__() method, whereas the
add_min_data() method will be used to add minimisation parameters.

Added the 'scope' arg to the specific API param list add() method.

This will be used to merge the GLOBAL_PARAMS and SPIN_PARAMS lists into one.

Created the specific API param list loop() method for looping over parameter names.

All the get_*() methods of the specific API parameter list objects now call self.check_param().

This new check_param() method raises a RelaxError if the parameter is unknown.

The parameter set 'params' or 'generic' can now be specified in the specific API parameter lists.

Big fix for the auto-generated GUI user functions - the recycling of pages should now work.

The recycling of user function pages was failing due to the wizard _exec_count data structure. A
click on the 'ok' button increments these counts, and a subsequent _ok() call was then suppressing
the execution of the user function. The GUI tests were missing this, as the _ok() call was
bypassed by calling on_execute() instead.

Fix for the Python types structure in the specific API parameter lists.

The GUI tests _execute_uf() base method now simulates a click on the 'ok' button.

This gives the user function wizards a much deeper work out.

Renamed the Python type arg from 'type' to 'py_type'.

Added the 'min_stats' flag to the specific API parameter list objects.

This indicates if the minimisation statistics are part of the parameter set. This is a flag to the
__init__() method, as it applies to the entire parameter list.
