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.

Fixes for the changes to the dispersion experiment type variables throughout the dispersion code.

Another change to the dispersion experiment type variables.

Clean up and expansion of the dispersion experiment type variables.
