prepend PointerHandler children of Items so the last is visited first

This helps with overriding behavior: when a QML control implementation
has handlers encapsulated inside, but the user tries to override
behavior by declaring more handler instances in instances of the
control, the user's handlers must be visited before the encapsulated
handlers.  Likewise, this reverse-ordering corresponds to intuition
after having used MouseHandlers: the one which is declared last inside
an Item will have a higher effective Z order, and thus will be visited
first during event delivery.
