Mostly using autowiring to inject deps.
The only tricky part was for import because all producer use the same class and have a different alias. So we must write them down in the service definition, autowiring doesn't work in that case.
Usually:
- if a controller has a constructor, it means injected services are at least re-used once in actions
- otherwise, service are injected per action
Thanks to the BC compatibility, almost nothing have to be changed.
All changes are related to new bundle version of:
- SensioFrameworkExtraBundle
- DoctrineFixturesBundle
