Graphics/Validate problem solved: Defined arch.diagram showed e.g. in
SAP 4 assignment a lot of violations from Define to all other modules
(all with the same number of violations).
Cause: Bug in Validate...Filtercontroller included all violations from
Define to itself.
Graphics problem solved: Modules in Defined Architecture Diagram did not
show their type/stereotype.
Main changes in FigureFactory and ModuleFigure.
Furthermore: Logging info improved.
Graphics problem solved: Ugly line layout; overlapping lines; lines
begin and end at strange positions.
Mainly because of a bug in Drawing.
