Custom settings when creating a new game. In a human readable file format.

Place all of the custom settings in a custom.ini or custom.json file.
This will allow me to make different presets for various play styles and/or maps.
Currently none of this is remembered and I have to change the settings every time I start a new game.
It might be used for advanced users and would probably take less time to code for the Developers than other options.

Probably should be combined with my other keybind.ini suggestion. Oops!

And this would let us to send startup profiles to others.
For instance, if a Youtuber were to post this in their Let's Play video, we could start our game exactly how they do.
This can be done by sending a save game to others, but I would not know exactly how this save game was created without seeing a picture of anothers startup configuraiton.
