Restored the Py_INCREF() function call in the relaxation curve-fitting C module.

This was deleted at r12632 along with Py_XDECREF() and Py_DECREF() calls. The absence of a
Py_INCREF() function call causes the module to crash the Python interpreter under certain
conditions. The problem was found in the relax_disp branch.

Changed the 'Execute relax' button in all analyses in the GUI to 'Execute analysis'.

It makes no sense to execute relax as relax has been executing during the analysis initialisation
and the user setting up all the data for the analysis. This is a remnant of ancient design of
Michael Bieri's GUI being a separate program to relax, which would execute relax with the click of
this button.

Added the relaxation dispersion graphic to all of the dispersion GUI user functions missing a graphic.
