Rename Development Front-Controller

If you're going to be developing a lot then even a small change of renaming "app_dev" to "dev" will speed things up when you have to type in the front-controller filename a lot.
Update Application Kernel

On kernel boot, register the application logger (Monolog) with the error handler. All errors will now be logged with Monolog's handlers in the configuration.
Add FOSUserBundle

Add the UserBundle from Friends of Symfony (add as a dependency to the Composer configuration and register bundle with the Application Kernel), and update the application and security configuration to reflect this bundle.
Use Raven Handler in Monolog

Add the Raven Sentry client as a dependency of this project, so that a new handler can be added to Monolog to send logs and errors to an external server.
