Change AWS request signing to allow AWS requests to be sent through the Runscope Inc. (https://www.runscope.com) Traffic Inspector.
Fix to encode : and / in parameter values correctly (e.g. for AWS arns query string arguments).
Make the version of the AWS request signing algorithm an explicit part of the interface (awsAuth AWSv4 ...) because there is no guarantee that all AWS services would implement a new signing specification (if there every will be one) at the same time. To be ready for this eventuality, layers above Wreq should maintain a table to record which AWS service should be called using which signing specification version. Currently all AWS services support version 4 (AWSv4), which is the latest version as of 2014.
Tiny simplification for readability.

Multiple AWS-specific improvements and a small, but important fix
