GUI: Menu and clickable images

[Michael Hartlef]

Hi folks,

I used Petr's GUI example as a base and came up with this system so far.
You can create a menu bar plus load images that react to clicks.


Please don't mind the dirty code, but I'm sure you will see the important parts.
There is a lot of unused code in it, mostly from an example of Petr.

Cheers
Michael
