public signal void item_changed (ComponentBagItem item)
A signal emitted whenever an existing item in the bag is changed.
It's a complement signal for the ECalComponentBag:ECalComponentBag:added signal, in a sense that when adding an item to the
bag either the added or the item-changed is emitted, if the component changed.
The item can be modified, but if any properties related to the layout changes then the content needs to be recalculated, for
example by calling rebuild.
