tabs, windows + gocui dropdown menu (almost)

    dropdown menu figures out what text was clicked
    dropdown menu movement changes line colors
    dropdown menus force user to select a response
    accidentally committed a binary
    tab selection works
    tab and window views almost working
    tabs and windows almost working
    window widgets selection works
    better color handling
    using gocui view.Visable flag
    removal of old color setting code
    still need an artificial delay for andlabs SetText()
    catching more 'nil' errors
    fixed the stupid duplicate tab problem in andlabs
    figured out how andlabs had a tab/box mess
    works on more than one domain
    builds and runs again
    debugging double tabs in andlabs gui
    GO111MODULE compile notes
    code reorg
    further improvements
    example cloudflare app does first successful dns update
    add NewEntryLine() for single line entry boxes
