bug #120 Add twig-bundle support (skalpa)

This PR was merged into the 2.0.x-dev branch.

Discussion
----------

Add twig-bundle support

Adds `symfony/twig-bundle` to the list of dependencies and registers the `@Twig` templates namespace.

- This fixes #109 and closes #110
- It also _fixes_ the exception page (eg: on `3.3` we get the fancy new page 😄 )
