Brought in chat sample app
Working chat sample
Fixed process.environment -> process.env
Forced xhr polling in the sample, websocket doesn't work in iisnode yet
changing require so that module references are not local, adding parameter for ServiceBus connection string
adding all references to package.json. Temporarily pointing socket.io-servicebus ref to github repo until published
Pointing to master branch
crlf issues
Changed argument order so easier to default sb connectionstring to environment
Merge branch 'merge-chat-sample'
