GUINumber
The number used by the GUI. GUI numbers start with 1 and there must not be two GUIs with the same number.

Attention: the specified GUI number must fit to the message box number of the RundownKernel/TreeManager. These two modules deduce the GUI number from the box used by the GUI. E.g. if you open ports 9981-9985 for GUIs then 9981=GUI1, 9982=GUI2, ... If you do not follow this rule connection problems might occur and the engine log will report an invalid GUI number.
