Dear me, I should have committed this long ago...

1) Added natives to create and manipulate global and private forward
2) Added natives to call forwards and functions
3) Added an IChanageableForward::RemoveFunction overload for convenience or something
4) Added test suite plugins for functions and forwards
5) Some random touch-ups to some include files
