cleanup of the example commands. more plugin workv0.4.6

    add a button in two plugins at the same time!
        added a button in andlabs/ui & gocui
    attempt a common widget struct between wit/gui & the plugins
    start handling missing plugins
    rename Makefile command examples
    remote examples used for testing
    filename improvements
    golang src code uses lowercase and _ in filenames
    fix crash when button click function == nil
    fix wrong name 'gocli' -> 'gocui'
    keep fighting with goreadme generated README.md
