Updated SourceCallback class to accept cloning, reversing, and visitors for saving./loading. New mechanism in Source to listen to key triggers for launching SourceCallbacks. Saving and loading in SessionVisitor and SessionCreator.
Translations are in a config xml file in settings directory, and can be directly edited in text by the user. Settings UI allows changing Ports for incoming and outgoing UDP.
Linear interpolation (instead of dichotomy converge) for fading at Session update. Mixing View update reads value of session fading to animate the cursor (which was preventing other manipulation of fading). Cleanup fading in OSC controller, with animation options and fade-in and fade-out controls.
Control manager will handle control actions, recorded or from OSC. Here skeleton for receiving OSC messages is in place. Cleanup of includes for NetworkToolkit. Touched a bit the BaseToolkit.
