Reviewers

There is now support for an in-memory cookie store. This feature can be
enabled via the --in-memory-cookies command-line option. For
consumers of the API, passing in_memory_cookies=True to the RBClient
constructor will enable this behaviour as well.

Ran unit tests.

Updated this review request with the --in-memory-cookies flag. I was
prompted for my username and password. When updating without the flag,
I am not prompted.
