Added support for custom order

[sarotnem]

Added another field in the configuration file so the language order can be specified.

Basically we define the order we want in the 'localesOrder' field.
Example 'localesOrder' => ['es','en']

Then in the blade file we output the language selector we call

<ul class="language_bar_chooser">
  @foreach(LaravelLocalization::getLocalesOrder() as $localeCode => $properties)
    <li>
      <a rel="alternate" hreflang="{{$localeCode}}" href="{{LaravelLocalization::getLocalizedURL($localeCode) }}">
        {{ $properties['native'] }}
      </a>
    </li>
  @endforeach
</ul>

and then the languages will have the order we specified. Don't forget to run php artisan config:cache after a config change

Can you add this function to the README.md? Thanks! 👍

For some reason Travis is failing with 5.6 and hhvm... Nothing but the readme.md was changed

Thanks for the changes! I'll take a look to the tests
