Replaced ContainerAwareTraceableEventDispatcher with TraceableEventDispatcher

The ContainerAwareTraceableEventDispatcher class was tied to both the
Symfony container and the HttpKernel profiler. It made it non reusable
in another context.

The new TraceableEventDispatcher only keeps the HttpKernel profiler
integration and is able to wrap any other event dispatcher. It makes it
reusable in frameworks using the Symfony HttpKernel component like
Silex.

The only drawback is that we don't have access to the listener
priorities in the collected data anymore (but the listeners are still
ordered correctly). The change is still worth it I think.

[WebProfilerBundle] moved all static assets directly into the templates

This has been done for several reasons:

 * for consistency with the way we already manage the WDT icons;
 * it makes the WebProfiler independant from the location of the assets (and from the asset() function)
 * this is the very first step to make the WebProfiler useable outside the full-stack framework (more commits soon)

There is still one asset() call though, which will be removed later on.
[WebProfilerBundle] changed all includes to use the new Twig's notation
[WebProfilerBundle] avoid the usage of the global app variable
[WebProfilerBundle] removed dependency on the templating component
[WebProfileBundle] remove dependency on the DIC

The controllers are not relying on the DIC anymore and only Twig
is used for rendering (instead of the Templating component).

The Exception controller has not been updated yet as it relies on many
external dependencies (and other bundles).

[TwigBundle] Moved the registration of the app global to the environment

This makes the app global variable available also when accessing the Twig
environment directly instead of using the TwigEngine.
