overrode MyGUI::DataManager::isDataExist

Browse source 
Created a override of MyGUI::DataManager::isDataExist to fix a
performance issue with MyGUI startup. This required moving the
functionality of MyGUI::OgrePlatform into OEngine::GUI::MyGUIManager so
that a new version of the MyGUI::DataManager could be created.
