Partial updates

[nerdoc]

Sometimes, especially on big components, not the whole component HTML must be rerendered, but just a small part. It could be helpful if only this part is rendered and morphed into the DOM at the client on demand.

This could be done using a manual parameter on update(partial="#somediv_id"), or better directly using a separated update_partial(id="somediv_id") in a public method.

Love this. Something I can look into
