[TYPO3-mvc] RFC #12442: Add type json to escape viewhelper

[Kevin Ulrich Moschallski]

Hi all,

this is a SVN patch request.

Type:
=====
Feature

Bugtracker:
===========
http://forge.typo3.org/issues/12442

Branches:
=========
trunk

Problem:
========
i suggest to add type json to the escape viewhelper.

Sometime you want to render json output with fluid and not with an own 
json view. The problem is that fluid also uses json like syntax, so if 
you want to add an object to a json string you run into a problem.

Imagine adding a link with the link viewhelper. It returns a sting with 
double quotes which need to be escaped for json.

Solution:
=========
I simply added type json to the escape viewhelper which returns the 
$value json_encode()'ed.

Regards,
Kevin
