data: basic template parsing

* Implemented basic parsing and storage of template parameter types, template classes and template functions
* Added template specialization edge.
* Implemented handling of partial specializations. Needs some more tweaking.
* Added a lot of test code for template stuff (still needs some cases to be tested)
* Removed the isTemplateParameterType from DataType, since it shouldn't be needed
* Function qualTypeToDataType uses clang PrintingPolicy to fetch the desired format.
* Merged a lot of code for getting the correct names and name hierarchies of definitions
* Removed TokenComponentDataType
* Merged both of the Storage::addTypeEdge(...) functions
* Added "-fno-delayed-template-parsing" flag to parser for parsing test code.
