Argument to_json added to json function in Base view. Its value (which should be a boolean) determines if the data should be converted to a JSON object. Therefore if someone has already a JSON string and wants to return it in a HTTP response, he or she may set to_json=False and the object will not be converted.

tinyMCE.addI18n('en.example',{
	desc : 'This is just a template button'
});
