Title: Adding json_decode filter as revert of json_encode filter

Giving opportunity to pass object/array at params in twig by encode them
by json_encode and decode, after passing them via param, via new
json_decode.

Thanks that we can encode array/object, pass them by include, macro, etc
and decode at new template.
