Chained Message and Show?

Currently we do
```
BlockUI("modal_user_edit_content").message("<h1 style='color:white;padding-top: 190px;'>Loading...</h1>");
BlockUI("modal_user_edit_content").show();
```

it would be better if can be chained

`BlockUI("modal_user_edit_content").message("<h1 style='color:white;padding-top: 190px;'>Loading...</h1>").show();`
