Fix for a fatal typo in the previous commit (r21493).

Created the pipe_control.sequence.return_attached_protons() function.

This is used to return a list of proton spin containers attached to the given spin.

Bug fix for the lib.structure.mass.centre_of_mass() function warning when the element is not known.

This warning was buggy and resulted tracebacks.

Added a placeholder for the relaxation dispersion citation to the citation chapter of the manual.

The bibtex entry for this will need to be updated later once the citation is published.

Improvements to all of the R1rho model descriptions in the dispersion chapter of the manual.

Added the 'TAP03' and 'MP05' models to the abbreviations in the user manual.

Added the 'TAP03' model to the relax user manual.

This is the Trott, Abergel and Palmer 2003 R1rho analytic model for 2-site off-resonance exchange.

The 'TAP03' model was already partly in the manual, however it was listed as unimplemented. All of
the tables and the dispersion chapter text has been updated for the model.

Added the 'TAP03' model to the dispersion auto-analysis.

Added the 'TAP03' model to the GUI model list.

Updated the Relax_disp.test_tp02_data_to_tap03 system test numbers to match the optimised values.

These were so close to the MP05 model values that the test was passing anyway.
