[WebProfilerBundle] Added feedback about the current symfony version

Description
---

This PR adds some visual and textual information about the Symfony version that is currently used. It'll indicate when the used version has reached eom or eol. I hope this will make people more aware of the fact that they should update (as I've seen quite some people using completely outdated Symfony versions).
