Note
```php
<?php echo Form::label('roles', 'Roles:', array('class' => 'control-label')) ?>
```
instead
```php
<?php echo Form::label('roles', __('Roles'), array('class' => 'control-label')) ?>
```

For @dishuostec and other translators:
Don't use a colon in the rows are to be localized. This can cause problems, and the overhead of the translation interface
