Title: Improved use of Boto 

Boto supports a number of ways to set AWS credentials, including a local `.boto` file which is what I use. Here are the others:

I also added a wrapper around the connection creation to gracefully handle exceptions such as AuthFailure when bad credentials are used. Better than a Python traceback.
