RC3: docs issue with onCollision()

This is not a bug because it's technically correct in TGB Referece.pdf. But if you look at the t2dSceneObject callbacks, the 1st parameter is always %this, except for onCollision().

Quote:onCollision(%srcObject, %dstObject, %srcRef, %dstRef, %time, %normal,
%contacts, %points)

should be changed to this for clarity:

Quote:onCollision(%this, %dstObject, %srcRef, %dstRef, %time, %normal,
%contacts, %points)

Technically it doesn't matter though.
