removed unneeded json_encode / json_decode for 3 reasons:

- it's available natively since IE8 and it's provided by Chrome Frame which is a requirement for old IE
- it's only used for postMessage exchange which is a newer API than JSON
- if ever we would need it, it should be added in an external lib, not inside the editor code itself
