logic: expanded indexer to cover more template argument related elements

* recording of usages of FunctionProtoTypes (e.g. "int(void)" can be used as a template argument)
* implemented solving names of dependent template specialization types (these are not as bad as it sounds ;) )
* implemented correct solving or decayed types
* fixed: qualified type usages are recorded in the correct context
* changed cxx indexer tests not to crash anymore when something is not found
