when region not set for profile, awsume should set the default region

[felipe1982]

most of my roles/users in .aws/config do not have region set. I expect awsume to fall back to the [default] region and set the AWS_REGION env var appropriately.

Instead, the AWS_REGION remains unset.

I have released an update , 1.3.2, that will use the default profile's region when the profile Awsume is using does not have a region listed, which will be set to the AWS_REGION environment variable.

Thank you for the suggestion!
