    app: add standard highlight colors to gimphighlightablebutton.h
    
    We're currently only using GimpHighlightableButton in the layers
    dialog, which defines its own set of highlight colors.  We're going
    to use highlightable buttons in the dashboard too, so let's move
    the highlight colors to gimphighlightablebutton.h, and give them
    standard names.  We currently define
    GIMP_HIGHLIGHTABLE_BUTTON_COLOR_AFFIRMATIVE (green), and
    GIMP_HIGHLIGHTABLE_BUTTON_COLOR_NEGATIVE (red).
    
    (This commit was accidentally dropped from the gimp-2-10 branch; it
    should have gone before 40ac4f7bc0f43aee24dc7ae1cf674d1a59612f55.)
