Instead of using string contents for type identification use the address of a constant string array. This should speed up type verifications a little sind we only need to compare one machine word instead of a full string. Also, this saves a few strings. To make clear that types must be compared via address and not string contents 'type_name' is now called 'type_id'. This also simplifies the macros for declaring and defining public and private subclasses.
