Fix outline color on CCLabelTTF.
SetFnt will throw an exception if the font parser doesn't return something valid.
NSAssert replaced so any environment can handle the exception.
The problem is a bit further down the setter: createFontChars can crash with a SIGSEGV when the config is not valid.
Added objc_requires_super attribute to onEnter/onExit CCNode methods

- Also included onEnterTransitionDidFinish and
  onExitTransitionDidStart methods
