Title: [WIP] Roles

Couple notes:

* I stuck with just `:app` and `:db` - I think adding `:web` just makes things slightly more confusing considering if you're using Symfony, it is probably a web **app**lication. Thoughts?

* Some commands already had the `:db` role but were actually running Symfony commands - I changed these to `:app` because you shouldn't have to deploy your whole codebase+PHP to a database server. Thoughts?

* Added `:once => true` to tasks that should only be run on one server (if using multiple).
