Added setName and getName to IGUIElement, the same way as it's in ISceneNode. Note: I don't yet add a function like ISceneManager::getSceneNodeFromName to IGUIEnvironment as well. The reason is that current implementations of related functions ISceneManager::getSceneNodeFromId and IGUIElement::getElementFromId are done very different and I first have to figure out if there's any way to reconcile those sanely.
