If a template with an `<!--#inlude -->` tag  is configured with an "virtual" containing a `'` ; the HttpCache will generate invalide php code.

See #11845 for the same issue on `<esi>` tags

This supersedes the PR #11197 (while including the changes made by it). I removed the `$options` argument for `Symfony\Component\Translation\Translator` and replaced it by a public method `enableCache($cacheDir, $debug = false)`. It aims to solve what @fabpot said about passing an array of options in #11197 
while not modifying the existing constructors
.

The NotFoundActivationStrategy class from MonologBundle is totally independent of the framework and should be part of the bridge instead. That would allow people to use it easily with Silex for instance.

Previously, one had to be careful to check if the ``debug.stopwatch`` service was available before using it. Otherwise, the application would break in the prod environment.
