* Source/NSObject.m: ([methodSignatureForSelector:]) modified to take
into account any protocols that the receiver conforms to, so the
returned signature has the fullest possible type information.
Category Protocol(Fixup) ... evil hack to work around runtime bug.
* Source/GSFFCallInvocation.m: Fetch method signature from receiver
in preference to using other info. Ensures we have correct info for
the object we are sending the message to.
