gocui: working towards correct layout

    make a gocui widget binary tree
    more debugging cleanups
    sample button app displays in gocui
    geometry logic closer to correct
    improvements in gocui layout
    continued attempts to clean up tabs
    dump binary tree
    moving towards proper chan callback()
    deprecate Widget.Name
