Implemented to the front_end of the value.copy, a "force" flag to overwrite destination value.

Implemented to the back_end of the value.copy, a "force" flag to overwrite destination value.

Revert of commit r25002 in branches/R1_fitting.

This was not the correct implementation, since copying of 'R2eff' is
not really a "parameter", which can be "fitted" in the sence of the dispersion models.

Rather, R2eff should be copied, with value.copy() function.

Spelling fix for the is_r1_optimised() function name.

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.
