Update this line
Specifically, not just "usable" keys. And the type might be wrong too.

Done.

Wasn't SessionReady used for prefixed's keyadded event? If so, do we have
another way of triggering that event?

[jrummell, 2014/12/17 19:17:19]

Neither CDM_6 nor CDM_7 generate the ready event. Currently ready is generated
for the prefixed API when the update() promise is resolved
(https://code.google.com/p/chromium/codesearch#chromium/src/media/cdm/proxy_de...).

-   * The session is now ready to decrypt the media stream.
-   *
-   * Note: The above describes the most simple case. Depending on the key
-   * system, a series of <code>SessionMessage()</code> calls from the CDM will
-   * be sent to the browser, and then on to the web application. The web
-   * application must then provide more data to the CDM by directing the browser
-   * to pass the data to the CDM via calls to <code>UpdateSession()</code> on
-   * the <code>PPP_ContentDecryptor_Private</code> interface.
-   * The CDM must call <code>SessionReady()</code> when the sequence is
-   * completed, and, in response, the browser must notify the web application.
-   *
-   * @param[in] web_session_id A <code>PP_Var</code> of type
-   * <code>PP_VARTYPE_STRING</code> containing the session's ID attribute of
-   * the session that is now ready.
