Fix for the arg_check.is_list call used in the fix at r16130.

This now will return the answer rather than raising a RelaxError.

Changed the behaviour of the arg_check module so that the functions can return answers.

The raise_error flag is now accepted by all is_*() functions. If this is False, then the functions
will return either True or False, answering the question. This should allow the functions to be
used more extensively.

Fix for the call to arg_check.is_list() in the model-free code.

Improved the relax_data.read user function docs to stress the importance of frequency!

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

Improvements for the consistency_tests.set_frq user function descriptions.
