rbt username and password

[Eric Snow]

The auth credentials you need for rbt (reviewboard CLI) are easy to
miss in earlier emails that have this info.

username: <github username>
password: oauth:<github username>@github

As always, please let me know if you have any feedback on
ReviewBoard/rbt or need a hand spinning up on ReviewBoard.

Bonus Info:

You will only need this information the first time you use "rbt post".
After that it is cached (unless you clear that cache or otherwise
force rbt to authenticate).  The password piggybacks off OAuth
authentication you have already done via your browser.  This is
necessary since users are set up without passwords.
