Added +x flag to be able to run with bundle exec.
+x didn't work so no point in doing it then :)
Use the newer websocket-driver gem rather than websocket-protocol, since the latter seems quite abandoned (and there's been a bit of new development coming in websocket-driver).
Updated dependencies for the Gem also.
Use bundler so that we use the proper (bundled) version of the gems + added roundtrip example (utilizing the Reel roundtrip example).
Merge pull request #8 from perlun/master
