Title: Allow eucalyptus region to be configured via ENV

I tried to keep this as simple as possible.

Eucalyptus users will need to:
* Set "eucalyptus" as the region
* Source their eucarc file or manually export the following environment variables
* EC2_URL
* S3_URL
* EUARE_URL
* AWS_ELB_URL
* AWS_AUTOSCALING_URL
