Proper labels and descriptions for inspections

[drunken-monkey]

First off, thanks for your great plugin!

However, after enabling it some of my service calls got marked with a "weak service" warning. I have no idea what that means. Looking in the inspection settings, all of the Symfony2 inspections lack a description, and all four under "Service" have the same label:

Sorry I can't fix this myself, since (as said) I don't know what any of them really do. But could you please fix the keys and provide some descriptions? What is a "weak" service or route?
