Modified all of Troels' dispersion profiling scripts to work with older relax versions.

This is in preparation for obtaining some powerful timing statistics. The calls to the r2eff_*()
functions are unnecessary and are the only failure point in the scripts between the current code in
the disp_spin_speed branch and trunk or older versions of relax. So these function calls have been
eliminated.

Split systemtest test_r1rho_kjaergaard into test_r1rho_kjaergaard_auto and test_r1rho_kjaergaard_man.

This is to test use of the manual way to analyse.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Renamed systemtes test_r1rho_kjaergaard to test_r1rho_kjaergaard_auto.

This corresponds to the use of the automatic analysis method.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Split the systemtest test_r1rho_kjaergaard into a setup function, and a test function.

More stability fixes for the relaxation dispersion target function initialisation.

The target function can now be initialised when the r1 and chemical_shift arguments are None.

Typo fix from the previous commit.

The relaxation dispersion target function can now be set up when the optional frqs_H argument is None.

This allows the profiling scripts to run.

Made changes to the dir argument of systemtest Relax_disp.test_r1rho_kjaergaard.

This is to prepare for:
sr #3124 (https://gna.org/support/?3124): Grace graphs production for R1rho analysis with R2_eff as function of Omega_eff
sr #3138 (https://gna.org/support/?3138): Interpolating theta through spin-lock offset [Omega], rather than spin-lock field strength [w1]

This is also to test an expected bug, if R1 is not loaded.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Removed superfluous check, after the returned data is now in right structure.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Used the new class function: get_back_calc(), to get the data in the right structures when interpolating for graphs.
