This CL adds the "request pairing" implementation between the web-app and the host. Specifically:

* Adds a pairing registry to the Chromoting host.
* Checks the state of the "remember me" checkbox and sends a pairing request if needed.
* Adds the plumbing to get that request to host, and to get the response back to the web-app.
* Saves the pairing response to local storage, and uses it next time we connect.
* Uses Base64 throughout for the secret, since unencoded random strings can't be serialized via PPAPI.

Note that pairing is still disabled because we're still missing per-platform Delegate implementations, a UI for revoking pairings, and policy support for disabling the feature.
