Convenience factories for Border and Background

Getting this moving again as well.

This is possible, but I don't think it saves much. This API in Color makes
it easy to create a color, so just using that directly in the
border/background seems convenient enough to me. Comparing
    Border.rgb(125, 100, 75);
with
    Border.of(Color.rgb(125, 100, 75)); // whatever the method name ends up
being
tells me that funneling all the color creation ways into one method in
border/background is efficient enough to not merit multiple methods.

We could also mirror the named color constants, which would enable a

This is very similar to how "red" or "blue" are valid values for

I rather not duplicate hundreds of constants just to be able to do
    pane.setBorder(Border.RED);
instead of
    pane.setBorder(Border.of(Color.RED));
