Massive refactor to use go plugins. This is neat.

    update README.md
    set xterm title. make os.Exit() default on window close
    add a toolkit.Widget to the node structure
    remove 'Greeter' symbol mapping scheme
    removed the testing greeter code
    plugins:
        attempt to load plugins in a sensible order
    andlabs/ui:
        working andlabs/ui plugin (andlabs2)
   	buttons work in andlabs plugin
	TODO: re-implement non-plugin version for Windows
		mswindows doesn't support go plugins yet
    gocui:
        put the gocui console so file in the binary
        does a full init of gocui plugin
        Button() and Group() working very well with gogui
    	cleanly exit gocui
    technically you can load two toolkits at the same time
        kinda both working at the same time. esoteric
        two working plugins at the same time
        give up working on two gui's at the same time
        this is fun, but _not interesting
        wow. this actually works. NewButton() from both toolkits
    examples:
        all the examples run again
        remove early helloplugin example
        buttonplugin example cmd code
        buttonplugin runs and ldd is minimum
