Some fixes: 

* [lua] Reverts 'removing tolua.cast in test case, I don't know why it was re-added.
* Some warning fixes in TriggerMng.cpp and TriggerObj.cpp
* Comment some lines in CCEditBoxImplIOS.mm/CCEditBoxImplAndroid.cpp, since after re-implement LabelTTF by Label, '(g|s)etTextureRect' will not work, it's because LabelTTF is inherited from Node rather than Sprite now.
We need to fix this as soon as possible.
