Better backwards compatibility of old relax results and state XML files for the interatomic design.

The MoleculeContainer._back_compat_hook() method has been shifted into the
Relax_data_store._back_compat_hook() method. This allows the spin containers with attached protons
to be converted (with new spin containers for the attached protons added) after loading of the XML
state.

Converted the bruker.read user function to the interatomic data design.

Converted the Angles.test_angles() system test and associated script to the interatomic data design.

Converted generic_fns.angles.spheroid_frame() to the interatomic data design.

The spin container hidden objects are now replicated when the object is copied.

The old Prototype.__deepcopy__() method was skipping all hidden objects, but now only objects
starting with '__' are skipped.
