[GREENFOOT-662] Move the background message functionality to GreenfootStage
GreenfootFrame has some functionality to show a background message hint in various circumstances, such as when there is no world, or it is taking too long to initialise. You can look at the call hierarchy of GreenfootFrame.updateBackgroundMessage() to see all the cases. This should be ported to GreenfootStage, which will involve two parts. One is simply adding the GUI components necessary to have a background message in GreenfootStage. The other is finding all the Debug VM callers of the original method, and translating that into calls on the server VM. In many cases this may make things more straightforward, but it will involve a bit of work.
