Here, at last, is my revision to the engine. Two new commands have been added - "assets", which allows you to define assets in a command, and "ops", which allows you to create an option dialog in a text box that will send a user to different scenes depending on which option they select. I've also created two libraries for pulling game data from an XML file or from a web service. The XML game data service object is now the only part of the engine that processes XML (though there may be a few lingering XML bits in the asset and command files). The game data is now handled entirely in the form of Javascript objects.
