Merge pull request #14 from philidem/master

Changes: error bubbling during widget initialization, widget notify method, IE7 stylesheet loading fix
Added code to prevent memory leak by detaching global document events and automatically invoking success callback for CSS loading after 300ms
Notify cannot be used as a synonym for "publish" since "notify" used to have old semantics and we need to maintain backwards compatibility
Disabled exception bubbling for widgets rendered on the server, but kept exception bubbling for widgets initialized on the client.
