Fix for bug #20420 (https://gna.org/bugs/?20420).

The problem was in the generic_fns.mol_res_spin.create_spin() function. The index_molecule() and
index_residue() functions where not taking alternative, non-current data pipes into account.

Added a second data pipe with data to the 'align_tensor_mc.bz2' saved state to catch a bug.

This bug was recently introduced.

Spun out the maths_fns.rotation_matrix.random_rot_axis() function into its own module.

The function is now called maths_fns.vectors.random_unit_vector().

Fix for bug #20417 (https://gna.org/bugs/?20417).

The backwards compatibility hook for the loading of old relax state and results files can now handle
the presence of proton spins. The data structures are now correctly converted to the current data
pipe design. This is only the case for old files containing PCS data.

Modified the align_tensor_mc.bz2 save file to catch a strange and rare bug.

This is caught by the State.test_align_tensor_with_mc_sims system test.
