PDFTool: Changed layout rendering of bottleneck infobox. Rationale: There is a conditional warning for bottlenecks necessary which have a ZPG Exception for their respective survey data. This line has to be added to the existing information in the bottleneck infobox. Therefore the layout has to be a bit more dynamic - depending on status of said condition having this exception. The existing code was enhanced to take this fact into account. A spacer variable was used for spacing between bottleneck info and the according legend. The layout of the bottleneck info grows dynamically. The overall optics where a bit streamlined.
