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()
- Adds `CC_REQUIRES_NULL_TERMINATION` to methods that require a NULL at the end
- Removes more Hungarian notations in samples
- s/sprite/scene: fix from previous commit
- `CCLog` -> `log`
- `getLayerNamed` -> `getLayer`
- `getPropertyNamed` -> `getProperty`
- and other small fixes
- 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)
... instead of sharedXXX / purgeXXX.
They are more C++ friendly, and also easier to remember.
common files + Mac files + iOS files + tests/samples files were updated.
The old methods are deprecated now.
