Candle RAD - added code syntax highlight

Added code syntax highlight for the controller 's action and template
Template simple parsing

Templates now support shorthand expression parsing
Example:
<p> This code will output {{foo}}</p>
Will be parsed as
<p> This code will output <?php echo $this->foo; ?></p>

Example:
Input: <p>{{foo.bar.baz()}}</p>
Output: <p><?php $this->foo["bar"]->baz(); ?></p>

Example:
Input: <p>{{url('main', ['action': 'self'])}}</p>
Output: <p><?php echo $this->url('main', array('action'=>'self'); ?></p>
