 We have a handy `remove_action()` function, but it works only if you can
 acquire the exact callback that was passed to add_action(), which is
 tricky when it comes to:

 * class instance methods, where you don't have access to the instance
 * PHP 5.3 closures

 Introducing namespaces for hooks, similar to jQuery's
 [http://docs.jquery.com/Namespaced_Events namespaced events], we would not
 only take care of that problem, but also enable things like:

 * remove all callbacks to 'the_content' added by plugin X
 * remove all callbacks to the 'parse_query' action added by theme Y
