Title: [4.2] Fixed The Serve Command Checks

We don't need to check if we are running php 5.4 or greater in laravel 4.2, because php 5.4 is already the minimum version the framework will run on, so we can remove that check. I've actually replaced this check with one that checks if we're using hhvm, because the internal server is not supported by hhvm.
