[Idea] Add a new 'Random Settings' tab in the GUI

[Yanis002]

This tab would randomize the main tab and the other tab, with options to add or exclude settings you don't want to be random (you choose manually). Add an option to hide or show the settings, so the code behind this would be a "setting string generator", this tab idea would generate randomly a setting string that applies automatically.

Note that people use a python script to do something similar, it would be nice to have this directly in the rando GUI.
