Create a new Settings window that contains all settings in one place

[andrasfuchs]

We have a rather confusing solution for settings at the moment: we have multiple submenus and windows and even subwindows for advanced settings. They all can be shown or hidden and they can float around.

It would be much better to have one settings window with all our settings, grouped by their function. It would not just improve the UX significantly, it would also simplify the code by following the separation of concerns design principle.

I found another open-source Java projects that have such a settings dialog, it looks like this:

Relevant source code can be found here and here.

ControlsFX also has a similar sample application.
