Override other Grid constructor

Hello,
I just need to be able to use two parameters Grid constructor, which allow to set autoCreateColumns parameter:

`public Grid(java.lang.Class<T> beanType, boolean autoCreateColumns) `


Can u add it? It should more less looks like this:
```
public PaginatedGrid(Class<T> beanType, boolean autoCreateColumns) {
     super(beanType, autoCreateColumns);
     init();
}
```

Thanks ;)
