<var>CheckChildrenHandles</var> recursively checks menu items to ensure that
handles for merged / child menu items are freed when they are hidden, or not
owned by a menu item on the menu. No actions are performed in the method when
Items has not been assigned.

<p>
At run-time, InitiateActions is called to ensure that the visibility of child
Items with an action are up-to-date. If AutoLineReduction is in effect,
RethinkLines is called to remove redundant menu separators. These actions are
not performed at design-time.

The handle for hidden menu items in MergedItems are freed. The handle for
visible menu items in MergedItems are freed and re-created.

CheckChildrenHandles is called from CreateHandle when the handle for a menu
item is allocated. It is also called when a menu item is merged into another
menu or item. Finally, it is called when update notifications are handled for
the class instances in the Items property.
