Title: [TwigBundle] Renames twig.loader to twig.loader.filesystem.

In the previous form of twig's service definitions, it was impossible to
use a chain loader correctly because the TwigBundle was registering paths
on the twig.loader service. This patch fixes that by creating a
twig.loader.filesystem definition and an alias twig.loader that points
to twig.loader.filesystem by default.
