AllowsMultipleSelectionDuringEditing not supported

[therealjohn]

If you use UITableView.AllowsMultipleSelectionDuringEditing with
Monotouch.Dialog. If the property is set to true, the click on the table (with
edit mode enabled) seems to be ignored (no selection happens). If there is an
Element.Tapped, it will be executed. In my current implementation it will push
a new UIView to the NavigationController, but this is not what you expect in
edit-mode.
