Should not include silex.phar in the repo

[Igor]

You can either add a submodule (PITA due to lots of nested dependencies), add instructions for fetching it into the README (simple wget command) or wait for composer to be ready, which will make this a lot easier.

I suggest you go with updating the README for now and I'd be glad to help you migrate to composer when the time comes.

Thanks, I'll glady accept the help. For now I removed the phar and added a note in the README.
