Updated the insignificance argument docstring for the dispersion auto-analysis.

A GUI element for the insignificance level for the dispersion auto-analysis has been added.

This defaults to 1.0. The user can input any number they wish. Checks were added for non-numerical input.

A number of fixes for the script UI section of the dispersion chapter of the manual.

The NUMERIC_ONLY variable is now explained and the R1rho MODEL list has been changed to a set of
reasonable models.

Added the 'No Rex' model to the R1rho_analysis.py sample script.

Updated script UI section of the dispersion chapter of the user manual.

This is for the recent changes to the sample scripts including the addition of the RESULTS_DIR and
INSIGNIFICANCE variables.

Added the insignificance dispersion auto-analysis argument to the Hansen CPMG data optimisation script.

Created an INSIGNIFICANCE variable for the relaxation dispersion sample scripts.

This is to allow the user to eliminate insignificant models.

The relaxation dispersion auto-analysis now accepts the 'insignificance' argument.

This is then used in the relax_disp.insignificance user function prior to the optimisation of each
model, so that spins with insignificant dispersion curves are not optimised. The 'R2eff' and
'No Rex' models are skipped for obvious reasons.

Improvements for the relax_disp.insignificance user function.

Text is now printed out when a spin is deselected. And all spins set to the 'R2eff' model are
skipped.

Created the new relax_disp.insignificance user function.

This will be used to deselect all spins whereby the maximum difference in all its dispersion curves
is below a certain cutoff.
