Add DEFINE_CLASS macro

Also made klass static field non-inline in order to properly allow for external linkage.

Update to avoid file logging

This is due to a bs-hook issue, related to a null deref when adding to file log buffers.

Update to fix perfect forwarding, rename macros

Deprecated DECLARE_CLASS_CODEGEN_INTERFACES for now
Renamed DECLARE_INTERFACE_METHOD to DECLARE_OVERRIDE_METHOD
Fixed DECLARE_CLASS_CODEGEN

Update codegen macros to provide proper inheritance

Modified some macro comments as well.

Add interface implementations, virtual methods, abstract classes

Added fields, interface implementations, virtual methods, abstract classes (with abstract method overriding).

Should be mostly functional, publishing to QPM!

Initial Release!

It is also released on QPM!
Functionality-wise, test.cpp should cover most core functionality. All useful headers also have doxygen documentation. See macros.hpp and register.hpp (along with types.hpp) for the core features.
