Improves SpriteTest.
It is easier to see if Sprite works as SpriteBatchNode (and vice-versa).
Needed for the new renderer.
Also adds `const` to title() and subtitle()
- Removes Hungarian notation from the CPP test (there are still some Hungarian to remove)
- Label and MotionStreak: Uses the CL() entry for the tests (lambda functions)
Handy macros for callbacks.
Instead of:
std::bind(func_ptr, instnace, std::placeholder::_1)
you use:
CALLBACK_1(func_ptr, instance)
And also removes more warnings from the tests
