Title: Inject event manager services into Connections

The problem was that doctrine-mongodb Connection services were never given an event manager, so they created a new event manager internally. The lack of event manager injection also meant that the compiler pass never attached listeners for doctrine-mongodb events (non-ODM events).

Given this limitation, I'm not sure how @jwage's [Logging MongoDB Explains](http://jwage.com/2012/02/22/logging-mongodb-explains-in-symfony2/) recipe could have worked, unless this problem does not exist for the bundle's Symfony 2.0-compatible version.
