Modified shebangs to use env to support NixOS

Thanks.

1. Branches have the following naming convention: feature/something-something.
2. Do not use your personal e-mail address, use @rev.ng.
3. Do not sign commits, if we'll ever do it, we'll do it in a coordinate way.

@zommiommy you have to fix the bullets above in order to get these in.
