Splitting command gui because it runs of screen due to too many commands.

[Gewerd-Strauss]

Since I have so many commands nowadays, my list keeps running beyond the visible edge of the screen. This patch will split the "command"-tooltip at the midway point and display both parts separately to both sides of the active gui.

Missing features might include a way to check if the tooltip is larger in vertical size than the screenheigth, and only then split the tooltip.

Is there a way to search the tooltip?
