API Version Defaults and Docs Update

API Version Defaults to Current Version

We no longer require accept-version or api_version to be passed in with every API request. If one is not provided, we'll use the current API version. Already have code using version? No worries! That still works just fine too.

Added redirect_uri to OAuth Docs

We've always validated the redirect_uri when used, but it wasn't documented... Until now! Learn more about how to use redirect_uri in our OAuth section.
