This commit also fixes exception pages when Twig is not enabled as a templating engine.
Instead of just displaying the raw Twig template as before, we now fallback to the default
exception handler introduced some time ago.

Non-blocking WDT & prevents garbage to slip in the page
I made the loading non-blocking so that it's not preventing normal operation of the page when the WDT takes a bit long to come up (happens sometimes when the machine is busy).
The second commit also checks that the response looks correct, to prevent stack traces and such to appear in the page if there was a problem. The main issue is not really stack traces though it's mostly with security and intercept_redirect enabled, if you look at a fully secured site you get twice the redirect intercept message to the login page.
Tested in IE7/9/FF4/Opera11
* Seldaek/events:
[EventDispatcher] Removed temporary code
[FrameworkBundle] Improved code readability
[FrameworkBundle] Clarified code and fixed regression
Update Core and Security events to latest model
[EventDispatcher] Allow registration of arbitrary callbacks
[EventDispatcher] Remove useless code
[EventDispatcher] Minor memory optimization to getListeners()
[FrameworkBundle] Small optimization, remove some function calls
The main benefit is that in XML/YML files we have common syntax (i.e. core.controller, form.pre_bind) that properly namespaces event names (before: onCoreController was ok, preBind was not).
On the other hand in PHP land we also have namespaced events, CoreEvents::controller, FormEvents::preBind, before it was Events::onCoreController, Events::onPreBind, we now have more context.
This in effect removes the direct link between event name and the method name on the handler.
Any callback can be given as a handler and the event name becomes an arbitrary string. Allowing for easier namespacing (see next commit)
