Lots of fixes for the model-free system tests.

Bug fix - the spin_id arg for the relax_data.read user function now actually does something.

This argument is passed into the pack_data() function, where it is used to match against the spins
matching each file line. Only if there is a match, is the relaxation data loaded for that spin.

The return_spin_from_selection() function now lists all matching spins in RelaxMultiSpinIDError.

Fix for the return_spin_from_selection() function for a bug introduced in the last commit.

The return_spin() and return_spin_from_selection() functions can now handle multiple spins.

It the 'multi' flag is supplied, then lists of spins (and associated data) will be returned, rather
than a RelaxMultiSpinIDError error raised.

Created the list_to_text() RelaxError system function for prettifying the output of RelaxMultiSpinIDError.

Expanded RelaxMultiSpinIDError to be able to print out a list of all the matching spin Ids.

Update and clean up of the model-free LaTeX table generation script.

Improvements for the MoleculeContainer backwards compatibility hook for the creation of proton spins.

The proton element and isotope type is now set to 'H' and '1H' respectively. This now means that
the old XML files require less work by the user to convert to the new interatomic data design.
