Create gitignore for Laravel5

In Laravel 5 the storage folder was moved to the root of the application. The compiled.php has also been moved to the bootstrap/cache directory

This was no longer compatible with the previous laravel.gitignore.

Laravel5.gitignore

+bootstrap/cache/
+.env.*.php
+.env.php
+.env
+.env.example
+
+vendor/
+node_modules/
+storage/
