Fix for the spin_id arg of the model_free.select_model() user function.

Wrote 7 unit tests for all args of the model-free user functions.

Added the framework for unit tests of the model-free user function args.

Converted all the res_num args to spin_id in the model-free user functions.

Copyright update.

Removed the run argument from all model-free user functions.

Deleted the model_free.copy() user function.

This function was not used anywhere within relax and the model-free specific copy() method was
complete rubbish anyway (ancient, unused, broken code).

Started to convert the model-free user functions to the new relax design.

Reverted r4656 which was itself a reversion of r4653.

The command used was:
svn merge -r4656:4655 .

This import uncovered a problem solved by r4659 and can now be committed again.
