b676df69da Add method decorators 
This required a new approach for handling function arguments.

Methods remain the same: the callee object is on the stack and positioned
to be "argument 0". Non-methods have changed so that "argument 0" is the
first argument, with the function still remaining before that. When a
non-method is called, we track this fact so that we can continue to restore
the stack to the correct height to get rid of the function. This allows
a method decorator to be defined exactly like it would be in Python

def methodDecorator(func):
    def wrappedMethod(instance, someOtherArg):
        print "Do something with the arg:", someOtherArg
        func(instance)

class Foo():
    @methodDecorator
    def func():
        print "I only take an implicit self:", self

let f = Foo()
f.func("but that other arg is needed")
