Added two functions for determining if a spectrum ID corresponds to a CPMG or R1rho experiment.

These are functions in specific_analyses.relax_disp.disp_data and they are called is_cpmg_exp_type()
and is_r1rho_exp_type().

Fix for the relax_disp.spin_lock_field pop up menu entry in the spectrum list GUI element.

Another action method bug - the same as in the last commit.

Fix for the relax_disp.cpmg_frq pop up menu entry in the spectrum list GUI element.

The method associated with the menu entry action_relax_disp_cpmg_frq() was buggy.

Fix for the relax_disp.exp_type pop up menu entry in the spectrum list GUI element.

This was calling relax_fit.exp_type rather than relax_disp.exp_type.

The GUI now warns if the user choses inappropriate models.

When clicking on 'Execute', an error message appears if R1rho models are selected for CPMG data and
vice versa. This is simply for more intuitive user feedback.

Simplified the code of the Relax_disp.test_hansen_trunc_data GUI test.

Large speed up of the Relax_disp.test_tp02_data_to_tp02 GUI test.

By minimising the number of times the peak intensity wizard pages are regenerated, the test time
decreased on one system from ~32s to ~12s.

Fixes for all of the GUI dispersion tests for the changes to cdp.exp_type.

This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about
supporting multiple data types such as SQ+MQ data simultaneously.

Fix for a bug introduced at r20855.

Added some sanity checks to the dispersion target function class.

R1rho models cannot be used with CPMG-type experiments, and CPMG models cannot be used with
R1rho-type experiments.
