Authorizations

I'd like to keep the commands as flat as possible while not ending up with many closely named methods. Here's what I came up with for tokens


* **authorize** - Create and store an API token using username and password
* **scopes** - List scopes for a token
* **tokens, authorizations** - Manage tokens
  * **ls, list** - List tokens
  * **create** - Create a token
  * **update** - Update a token
  * **delete** - Delete a token
