Created the Structure.test_rmsd system test.

This test checks the currently unimplemented structure.add_model and structure.rmsd user functions.

Added a printout to structure.delete for when no structures are present.

Fixes for the structure.delete user function.

This can now handle no data being present, the spin and interatomic data containers are now have
their structural data properly deleted, and printouts have been added so the user knows what has
happened.

Created the simple Structure.test_delete_empty system test.

This is to demonstrate a failure of the structure.delete user function when no structural data is
present.

Updated the Freecode instructions in the release checklist document.

Created the Structure.test_delete_multi_pipe system test.

This is to check that the structure.delete user function is operating on a single data pipe.

Changed the model order in the frame order auto-analysis to have a more logical sense.
