GUI - reworked to allow for event-based topology building, in preparation for web-socket connection to the server.
 - device nodes will enter in a fixed location, if metaUi data is included in the addDevice event.
 - device nodes now adjust their bounds to fit the text (and show an icon).
 - added cycle labels function (press the 'L' key).
 - links now appear with "transition" animation.
 NOTE: this is still WIP.
