Squashed commit of the following:

    all non binary tree structs are gone (almost all)
    Use names from https://en.wikipedia.org/wiki/Graphical_widget
    toolkit andlabs/ui is isolated from being accessable
        all direct references to andlabs are removed
    working dropdown widgets
    add debugging more buttons and windows
