Implemented the specific_analyses.relax_disp.parameters.r1_setup() function.

This matches the description at http://thread.gmane.org/gmane.science.nmr.relax.scm/22850/focus=6739
and http://thread.gmane.org/gmane.science.nmr.relax.scm/22850/focus=6736.

Implemented the very basic relax_disp.r1_fit user function.

This is as discussed at http://thread.gmane.org/gmane.science.nmr.relax.scm/22850/focus=6737.

Created the specific_analyses.relax_disp.data.is_r1_optimsed() function.

This follows from an idea for handling R1 optimisation in the tread at
http://thread.gmane.org/gmane.science.nmr.relax.scm/22850/focus=6736.

This relaxation dispersion function can be used anywhere that requires the knowledge that R1 values
should be fitted during optimisation or if loaded values should be used.

Fixes for the Relax_disp.test_r1rho_kjaergaard_missing_r1 system test on MS Windows.

This is for 32-bit MS Windows systems where the parameter checks need to be loosened.

Fixes for the Relax_disp.test_hansen_cpmg_data_missing_auto_analysis system test on MS Windows.

This is for 32-bit MS Windows systems where the parameter checks need to be loosened.

Fix to systemtest, after changing the keyword to the auto analyses.

Rewrote the logic of the key-word 'optimise_r2eff' in the auto analyses of relax disp.

If R2eff result file exist in the 'pre_run_dir', this is loaded.

If the results contain both values, and errors, then no optimisation is performed on the R2eff model.
Unless the 'optimise_r2eff' flag is raised, which is not standard.

Shortening the text in the auto_analysis, and raises a warning if R1 data has not been loaded.

Bugfix for Relax_disp.test_bug_21715_clustered_indexerror, where only 'R2eff', 'No Rex' is analysed.

This special case was not tested inte the translating function.

Made the GUI selection of models for relaxation dispersion more simple.

After the implementation of a function which will translate the models, the
'No Rex' model will be converted to the 'No Rex' model for R1rho off-resonance.

Also the corresponding 'R1 fit' model will be chosen istead, if R1 data has not been loaded.

This makes the model selection easier in the GUI interface.
