Don't deprecate callback functions in Layer. Reason:
Callback function should not be deprecated, it will generate lots of warnings.
Since 'setTouchEnabled' was deprecated, it will make warnings if developer overrides onTouchXXX and invokes setTouchEnabled(true) instead of using EventDispatcher::addEventListenerWithXXX.
Fix of unsigned / signed mismatch in UIPageView.cpp.
Removing unused 'virtual' keyword in testcpp since we're using EventDispatcher::addEventListenerXXX to register event listener.
Prevents warning of invoking ScrollView::setTouchEnabled. Layer::setTouchEnabled should not be a virtual function.
Add doxygen comments for the CocoStudio
Update tools/tolua/cocos2dx.ini, ignore onTouchXXX, onKeyXXX, onAccXXX callback functions to be bound to LUA.
