Fix tooltip height for versions of irrlicht < 1.8.2

Version 1.8.2 of irrlicht changed the way that IGUIStaticText::getTextHeight() works and since that release properly deals with newlines. From irrlicht changes.txt for 1.8.2, "IGUIStaticText::getTextHeight returns now the correct height for texts with newlines even WordWrap is not set."
