TActiveListItemCollection class.

Allows TActiveDropDownList and TActiveListBox to add new options during callback response. New options can only be added after the \Prado\Web\UI\TControl::onLoad event.

The \Prado\Web\UI\ActiveControls\getListHasChanged property is true when the list items has changed. The control responsible for the list needs to repopulate the client-side options.
