Hi, Jon.

I included a number of JSDOC AND SIGNATURE changes in the commit.

1. ManagedHub constructor
    * Added params documentation
2. ManagedHub.subscribeForClient
    * Added "throws" to jsdoc
    * Returns SubscriptionHandle
3. ManagedHub.unsubscribeForClient
    * Added "throws" to jsdoc
    * Added subscriptionHandle parameter
4. ManagedHub.publishForClient
    * Added "throws" to jsdoc
5. Hub/ManagedHub.disconnect
    * Added explanation of the effects of disconnect() on
        containers and subscriptions
    * Added "throws" to jsdoc
6. ManagedHub.getContainer
    * Added note that null is returned if no such container
6. ManagedHub.addContainer
    * Added "throws" to jsdoc
7. ManagedHub.removeContainer
    * Added "throws" to jsdoc
8. Hub/ManagedHub.subscribe
    * Added "throws" to jsdoc
9. Hub/ManagedHub.unsubscribe
    * Added "throws" to jsdoc
    * Added callback and scope parameters
10. Hub/ManagedHub.publish
    * Added "throws" to jsdoc
11. Hub.subscribe
    * Added "throws" to jsdoc
    * Returns SubscriptionHandle
12. Hub.unsubscribe
    * Added "throws" to jsdoc
13. Hub.publish

I think these were most of the change that affect the wiki page (which just
shows the interfaces). I can add these changes if it will help.

I have also made OpenAjax-mashup.js include the former contents of
OpenAjax.js. I could reverse this, but for now, when troubleshooting, this
makes life easier.
