* improved the way of gettig a TemplateSpecializationTypeLoc from any TypeLoc to parse template arguments.
* fixed wrong forward mouse button code in app settings.
* functions will only display their names in the graph view. hovering the nodes shows the signature as a tooltip. However, nodes in the database will be created and used regarding their signature.
* improved lambda handling. All calls to generated lambda functions (constructor, call operator) will now point to the lambda class instead.
* implemented handling of the "auto" type.
* improved the CxxParserTestSuite to use function strings instead of function names for template related functions.
* reverted to old source location retrieval for CxxConstructExpr, because source locations were outside file
* removed exisiting source location check for better performance
* fixed CXXParserTestSuite to use c++11 standard
* fixed crash on missing signature retrieval
* implemented handling lambdas as functions
* functions can have child nodes now
* NameElements in NameHierarchy can have signatures now.
* fixed crash that occurred when message listener was used while being half way through its destruction process.
