Create a more flexible json type. about flexigrid HOT 3 CLOSED

Hi folks, I'm here again, it was faster then I imagined. I managed to get the 
code working and now I can render a json into the format I did propose before. 

The diff file of the changes I've made follow attached.

As I said before, it can handle a json array of objects filling the table by 
the name of the columns get from the column model. I don't know if this is good 
for you, but it make my work simple and my java code become something like:

List<Client> clients = entityManager.createNamedQuery("Client.findAll", 
Estado.class).getResultList();
json.serialize(clients, response.getOutputStream());

So, it's really awesome to see it working :)

Hi, I'm here again... sorry by bother you with this bug report, this is my 
first time working with pagination. Now I realize why you need the other 
parameters as total, for calculate the pages. So, please close this "non bug 
report" :)

Sorry by waste your time ( and mine lol ).

For big and complicated data JSON with named keys are recognized.
