Using Twig classes even the twig configuration value is false

[mmoreram]

By default, twig value inside configuration is decided by checking if Twig_Environment class exists. That's great.
The point is that, after that, there is a listener that injects, always, a class that extends Twig_Extension. This makes that an application without Twig installed cannot use this bundle.

What to do:

• Place the twig related services to another file called twig.yml.
• Only load this file if twig is set to true
• Because the listener where this extension is loaded accepts a null value, inject a null when the service doesn't exist.

Thoughts?

Hey.

Thank you for your suggestions. You should have a look at version 2.0-beta. That is exactly what we have done.
