lint fixes and updated display values for ripple socket services
more of the way there for proxy
stop using ack for multiple callback examples (accel)
log when ripple + device disconnect, emit device-disconnect event to ripple, clobber ripple+device sockets blindly on every reconnect, switched from nested acknoledgement callbacks in socket.io to events.
proxy has a better idea of when it is ready or not now. added a DocumentLoad event that is triggered every time a new document is loaded in the iframe
