AutoUpdate: event/observer pattern

Based on this https://github.com/primefaces-extensions/primefaces-extensions.github.com/issues/358

I’d like to be able to write something like this:

<pa:menuButton icon="fa-shopping-cart"
               model="#{cartManager.cartModel}">
    <p:autoUpdate on="update-cart" listener="#{cartManager.createMenuModel}" />
</pa:menuButton>

<p:commandButton value="#{i18n['ADD_ITEM_CART']}"
                 action="#{cartManager.addItemToCart}" 
                 update="@obs('update-cart)"/>

on: attribute indicating the kind of event to observe listener: action to execute when update-cart is fired (before getting updated, being said I don’t know if we should have a pre & post listener?) @obs: retrieve client ids from components subscribing to the specified event

maybe ´@event´ instead ´@sub´?

yup
