added code to back off gracefully in case of authetication errors or disconnections. Note that the code is currently broken, as I'm in the middle of switching to OAuth authentication, required since June 2013
TweetStream module replaced with TwitterAPI module, which can handle OAuth, which is required for Twitter API 1.1 (since June 2013)
Merge branch 'master' of github.com:jorgehatccrma/TweetDreams
