Display under construction

So, now there's a display component - sort of - that will act as the display panel for the Watch Display.

This isn't a real Java component though. It's a classic 'game' design - there are a collection of BufferedImages() that draw onto another BufferedImage() which is then copied to the display.

You could split this up into components and layouts, but it would slow it down and it would be interesting to get it right.
