Fix the broken chatbox issue.
Revert this commit.
Removing this as jQuery is already included in Shimmie now.
Need to ensure that this html header is added last.
Chatbox should be fixed now.
The chatbox extension actually needs some functionality that was removed from jQuery versions 1.9 and up. When Shimmie's version of jQuery was bumped up to 1.11 this actually broke the chatbox.
Don't use short open tags for PHP as they are not turned on by default in production environments.
Again, the chatbox needs help from the jQuery migrate plugin.
One more jQuery reference.
