Enable the use of @lang and @choice for Blade Templates

I wanted to be able to allow the use of @lang and @choice for localization.

This meaning I'm now able to write my localized templates with the pretty Blade style and syntax.

    @lang('messages.key') // produces <?php echo Lang::get('messages.key'); ?>
    @lang('messages.key', array('variable' => 'replacement'))  // produces <?php echo Lang::get('messages.key', array('variable' => 'replacement')); ?>
    @choice('messages.key', 1)  // produces <?php echo Lang::choice('messages.key', 1); ?>
    @choice('messages.key', 10)  // produces <?php echo Lang::choice('messages.key'. 10); ?>
