Attempting to add namespaces
Fixed namespace issue.
Once we added namespaces to controllers, classes that were earlier loaded from global namespace (Controller, Auth, Response, Task, Tasklist), were now being searched in current namespace.

Note: hhvm was not logging any errors till I changed the log level to Verbose, after which there was a 'Fatal error:' log in the hhvm logfile. hhvm bug?
Missed Auth class in TaskController for namespace fix.
Merge branch 'namespaces'
