Fixes for the relax_disp.plot_disp_curves user function backend for the cdp.exp_type changes.

Fixes for the specific_analyses.relax_disp.disp_data.find_intensity_keys() function.

This is for the cdp.exp_type changes.

A few fixes for 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.

Fix for the new loop_exp_frq() dispersion function.

Missing import.

Fix for the dispersion auto-analysis for a bug introduced in the last commit.

The dispersion auto-analysis no longer references 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.

Added some functions to specific_analyses.relax_disp.disp_data for checking if certain experiments exist.

These are the has_cpmg_exp_type() and has_r1rho_exp_type() functions.

Fixes for the specific_analyses.relax_disp.api module for the relax_disp.exp_type change.

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 loop_exp*() functions are now being used throughout the module. The
specific_analyses.relax_disp.checks.check_*() functions are also used to simplify the code and fix
changes to cdp.exp_type. And some auxiliary functions from specific_analyses.relax_disp.disp_data
are being used as well.

Added a number of auxiliary functions to specific_analyses.relax_disp.disp_data.

These are get_curve_type(), has_exponential_exp_type(), and has_fixed_time_exp_type() and will be
used to simplify the dispersion code.
