Issue

#267

(explain: Browser starts immediately and access to the sign-out URL)

$ ./rain console -lu 
Open the following URL in your browser: https://signin.aws.amazon.com/oauth?Action=logout&redirect_uri=https://aws.amazon.com

Impact of this change
URL generation messages have changed.

before: Generating sign-in URL
after: Generating URL

Because, generated URL is not only sign-in URL.

Concern

This feature is tested only on Mac.
Not tested on Linux/Windows because of the time-consuming preparation.

Rain preserves your comments when using YAML and switches use of [intrinsic functions](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/intrinsic-function-reference.html) to use the short syntax where possible.

I guess the sentence is added directly.

using aws cloudformation package

Because the sentence doesn't appear in README.tmpl

May I add the sentence to README.tmlp?

[ericzbeard]

Actually I removed that one and haven't regenerated the README yet.

What about govcloud?
