PKEuS eb2962792f Implemented support for move constructors:
- Changed behaviour of Token::function - is now also set for declarations
- Resolved TODO in testclass.cpp

Changed behaviour of symbol database: Insert argument Variable of functions that are not implemented into SymbolDatabase::_variableList
