* This class provides a generic subscription widget

* show all changes. The user can change the state of the items via checkable items.
* When you construct a new instance you need to provide an account and a caption
* After inserting your items (checkable or not) you need to call slotLoadingComplete()
* You should at least connect slots to the signals okClicked() (to save your changes)
* and user1Clicked() (to reload the list)
* You can hide unwanted checkboxes via the respective hide<checkboxname> methods
