Enable compatibility and testing with Symfony 2.4

Hello,

Symfony 2.4 is scheduled for november then, according to Symfony release process, the stabilization phase should start in september.

I think it's a good idea to add Symfony 2.4 compatibility as it seems there's no breakage and some people would like to work on the 2.4 branch while working on Silex.
