Extract Settings to its own chapter about gitextensionsdoc

Yes, I fully agree.

I've made the change and pushed to my repo but I haven't currentlygot sphinx installed anywhere to check that it links okay, so I haven't made a pull request yet.

You can also create your own read the docs account and set up a hook to build the doco from your private fork of GitExtensionsDoc. But installing sphinx localy will give you a much faster way to see how your changes translate to the final html.

Thanks Janusz, that's good to know.
Haven't had much time this last few days but I installed python and sphinx, and the new pages link okay so all ready for a pull request.
