Added the spin specific relaxation data objects to the model-free data_names() return value.

Converted the global_flag arg to a keyword arg in get_data_names().

Partial fix for bug #11860 (http://gna.org/bugs/?11860).

The partial fix was to change the force flag to a bool in the diff_tensor_pdb.py sample script.

Updated the data_names() and data_init() methods to include more of the model-free data pipe objects.

Added spin object descriptions to the XML elements.

The SpinContainer XML elements are now sorted as in the relax 1.2 results file.

Removed the index attribute as the order of the XML elements is constant.

All molecule, residue, and spin specific data is now placed in the XML results file.

Shifted the module docstring to the top of the module.

Added molecular information to the XML results file.
