Parameters removed because they are not in use

CS Fixes

ET minor fixes

Call composer command to copy .env file

Moving this command first to keep 'php artisan optimize' from generating a
'compiled.php' since the .env has APP_DEBUG set to true.

If you run the installer to create a new project it says the
Application key was set successfully even though it wasn't.

This calls the composer script to copy .env.example to .env, so the
next script that calls artisan key:generate will work.

The reason for the current behavior is that php artisan key:generate
doesn't display an error if it fails to find a .env file.

Keep symbolic links in zip

The files in ```vendor/bin``` or symbolic linked.

Use the -y  for ```zip``` will keep the symbolic links.

Otherwise this will produce an error:
```sh
php laravel new test-app
cd test-app/vendor/bin
php ./phpunit
```
