This is the second try to my previous attempt to implement the new abstract class handling. Instead of a compile-time error, the VM now throws an AbstractClassInstantiationError at runtime if an abstract class is instantiated. Added the new error class to the core library. For now I'm still using the rule that a class is abstract if it is explicitly marked as abstract, or if it defines a new abstract method.
