The spectra list GUI element in the dispersion auto-analysis now shows all columns.

The CPMG frequency and spin-lock field strength columns are merged in the spectrum list GUI element.

The column is now for the dispersion point data, and allows different experiment types to be mixed.

Added the experiment type to the spectrum list GUI element.

This is only activated if the exp_type_flag argument is True.

Added the relax_disp.exp_type user function to the peak intensity loading wizard.

Modified the dispersion GUI analysis to handle the relax_disp.exp_type user function changes.

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.

The experiment type GUI element has been removed, the CPMG and R1rho model lists merged into one,
and much code for the experiment type removed. The peak analysis wizard will need to be heavily
modified for the changes.

Removed the relax_disp.exp_type user function page from the new analysis wizard.

Created the specific_analyses.relax_disp.disp_data.loop_exp*() functions.

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.

The methods added are loop_exp(), loop_exp_frq(), loop_exp_frq_point() and
loop_exp_frq_point_time().

The relaxation dispersion system tests requiring the compiled C modules are now skipped when not compiled.

Fixes for the relaxation dispersion system tests for the relax_disp.exp_type changes.

Redesigned the relax_disp.exp_type user function to be associated with spectrum IDs.

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.

The user function backend has been moved from specific_analyses.relax_disp.api to
specific_analyses.relax_disp.disp_data. A few temporary code additions have been made to keep the
user function functional with the current dispersion code.
