Manifest - oauth2

An optional manifest key enabling the use of an OAuth 2.0 security ID on the extension. This key takes an object with two required sub-properties: "client_id" and "scopes". When developing an extension that uses an "oauth2" key, consider also setting the extension's "key" to keep a consistent extension ID.
