Error in stack comparisson in deployStack method #95

When deploying a new stack, the deploy method compares a stringified version of the template. This is OK for the second step (cloudfront, SSL Cert, extra) but it is not appropriate for the first step.

The first step should get the generated object for the bucket and/or DNS. and see if the existing stack object (JSON) contains the bucket and/or DNS objects. if it does skip step 1.
