Added support for converting between kex and tex, and pA and pB for the dispersion analysis.

This is performed by the new specific_analyses.relax_disp.parameters.param_conversion() function.
For this, most of the code from the assemble_param_vector() function has been shifted into
get_value(), and most of disassemble_param_vector() into set_value(). The dispersion analysis now
also has a custom sim_init_values() method to handle these parameters.

Removed many decimal points from the MHz value in the Grace plots from relax_disp.plot_disp_curves.

The N-state model analysis can now handle RDC data of mixed D and T=J+D.

The Monte Carlo simulations now generate parameter errors for the relaxation dispersion analysis.

The simulation index was being ignored, hence the input data was never the randomised data and all
errors were zero.

The relaxation dispersion auto-analysis now outputs text and Grace files for all parameters.

This is in response to bug #20917 (https://gna.org/bugs/?20917) submitted by Troels Linnet
(https://gna.org/users/tlinnet).

The lib.io.open_write_file() function now catches file names of None and raises a RelaxError.

This is useful for the GUI if the user forgets to select a file name.

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.
