Fixed a typo in the new generic_fns.value.set() function.

Deletion of the set_non_spin_params() method.

This mess is no longer in the base API.

Massive simplification of the generic_fns.value.set() function.

This code was previously a mess, spread randomly across the generic code and specific code. This is
a complete refactorization which will cause breakages for a little while.

Added the set_param_values() method to the base API (matching the changes of r9986).

Redesigned the specific analysis API for setting parameter values.

Now the set_param_values() method is to be provided. It is for setting single parameter values.
This will be followed by a complete redesign of the value.set() user function back end (which is
currently a mess).

Specific analysis API clean up.

The get_param_name and get_param_value methods are returned by asking directly for these names.

Fixed all the calls to the renamed 'arg_check' module.

Removed 'check' from the __all__ list.

Renamed the 'prompt.check' module to the base relax directory module 'arg_check'.

This makes the module more available to other parts of relax that requires argument type checking.

Docstring fixes for the value.set() user function.
