Add callable render

[nicodmf]

I have no time to commit

But theres changes works :

<?php
//in ZfTable\Decorator\DecoratorPluginManager
class DecoratorPluginManager extends AbstractPluginManager
{
    protected $invokableClasses = array(
        /*...*/
        'cellcallable' => '\ZfTable\Decorator\Cell\CallableDecorator',
        /*...*/
    );
        /*...*/
}

And the new file :

<?php

namespace ZfTable\Decorator\Cell;

/**
 * Description of CallableDecorator
 *
 * @author Nicolas de Marqué <nicolas.demarque@gmail.com>
 */
class CallableDecorator extends AbstractCellDecorator
{
    protected $callable;

    public function __construct(  callable $callable)
    {        
        $this->callable = $callable;        
    }

    public function render( $value )
    {
        $values = array();

        $actualRow = $this->getCell()->getActualRow();     

        return call_user_func_array($this->callable, array($value, $actualRow));

    }
}

The call is consequently :

<?php

        $this->getHeader( 'template' )->getCell()->addDecorator( 'callable', function($value, $values) {
            return $v . $values['anotherfield'] . "called";
        });

Thanks for your plugin very usefull :)
