Fix for the relatively unused calc_tensor_diag() for oblate tensors.

The eigenvalues were incorrectly ordered for oblate spheroids.

Added 6 system tests for the spheroidal diffusion tensor.

Implemented the reading of model-free and CSA BMRB saveframes from NMR-STAR files.

Removed the model-free and CSA info from the blacklisted spin variables.

This is to test the implementation of model-free and CSA BMRB saveframe reading.

Shifted the core of the model-free _select_model() method into _model_map().

This allows other parts of the code to translate model names to model-free equations and parameters.

Restored the reversal of the rotation matrix when determining Euler angles for a tensor in the PDB frame.

Fix for the test_read() unit test of generic_fns.relax_data.read().

The relaxation data structures are now handled differently in this branch and all data structures
have the same from for all spins, even if data is missing.

A few system and unit test fixes broken by recent rearrangements of the diffusion tensor code.

Caught when no diffusion tensor data is yielded by the bmrblib loop() method.
