New sample that implements transport detection example

Hello,

I have a new commit suggestion that I implemented this afternoon, based on the Atmosphere Wiki example. I think it could also be a useful integration test to make sure that all the transports work properly. I hope you'll agree.

I have also taken the liberty to expand a little on the README file to explain how to compile the project (as I didn't immediately notice the usage of profiles), as well as the URLs to use for connecting to the samples.

Best regards,
  Serge Huber.
