WIP: feature(server): Add a forwarding proxy for IE8.

* Proxy auth server requests when the url is prefixed with `/auth`
* Proxy oauth server requests when the url is prefixed with `/oauth`

fixes #102
ahha, I edited my local.json file to point the oauth server to `https://oauth.dev.lcip.org`, allowing the tests to pass. If I use the default local.json, failures.
