Title: Lower dependencies for Rails 3.1 compatibility

Thanks for implementing the gem. I am happy to at least remove my own monkey patch and move all the behavior into one single place. Nonetheless I found out it doesn't support 3.1 and apparently I haven't seen any reason against it. I tested within my app and everything seems to work seamlessly (even my own integration tests towards the sendgrid endpoint).
