Update Environment.php

Now package's lang files in separate directory.
>Many packages ship with their own language lines. Instead of hacking the package's core files to tweak these lines, you may override them by placing files in the app/lang/packages/{locale}/{package} directory. So, for example, if you need to override the English language lines in messages.php for a package named skyrim/hearthfire, you would place a language file at: app/lang/packages/en/hearthfire/messages.php. In this file you would define only the language lines you wish to override. Any language lines you don't override will still be loaded from the package's language files.

For example, we can use ```app/lang/packages/ru/cruddy/entities.php``` It's more clear.
