Fix for the global settings window - it needs to inherit from UF_window!

This is an attempt at fixing bug #18197 (https://gna.org/bugs/?18197).

The old code has been completely eliminated and replaced with a new set of methods in the base
relax_gui class and a new Global_parameters class in gui.settings which is of the same design as the
free file format settings window.

All the result list boxes are now created by add_list_box().

The results tab now nicely resizes.
