Fix for bug #20910 (https://gna.org/bugs/?20910) - the broken grace.write GUI interface.

The problem was that the Value GUI input element was not detecting list-type data returned by the
wiz_combo_iter method.

Expansion of the modelling of dispersion data section of the relax user manual.

Import fix for the unit tests of the relaxation dispersion specific API object.

Import fixes for the gui.analyses.auto_relax_disp module.

Fix for the gui.analyses.wizard module for a bad merger at r20165.

Somehow svnmerge.py did not mark this file as being in conflict when it should have.

Import fix for the VAR_TIME_EXP dispersion variable in the gui.analyses.auto_relax_disp module.

Shifted the core of the relaxation dispersion API object into its own api module.

This is to simplify the relax import cascade - by removing the code from the
specific_analyses/relax_disp/__init__.py file, the import of the package no longer results in the
imports of other relax modules and packages.

This is from the import of the user_functions package to the package initialise() function. This is
for saner importing dependencies in the relax sources.
