Remove the build script

These archives do not really make sense anymore with Composer. And if people want to get started, they should probably use the Silex Skeleton instead.

Move setting $app['twig.app_variable'] after 'Symfony\Bridge\Twig' check

Currently `TwigServiceProvider ` sets `$app['twig.app_variable']` to be function that has a dependency on classes that are not required by Silex. This will fail if the user then calls that function. This happens for example when the [silex-pimple-dumper](https://github.com/Sorien/silex-pimple-dumper) maps over the app and tries to dump it's content.

This PR fixes that by moving this in the `class_exists('Symfony\Bridge\Twig\Extension\RoutingExtension')` check.

I've also added comment because at first it wasn't clear for me that this check for the `RoutingExtension` was the check for the whole Twig bridge. Please feel free to rebase and remove it it you don't like it or I misinterpreted it.

Keep up the good work! 👍
