[DragDropContext] Options: shouldDrop

[Vorlias]

Kind of similar to Roact.Component.shouldUpdate - Will allow you to control whether or not messages are passed from the source to the target.

This gives global control of drop behaviour, rather than individual control like DropTarget.CanDrop.

interface DragDropContextOptions {
    // This function allows controlling whether or not dropping works between target and source
    shouldDrop?: (target: DragTarget, source: DragSource) => boolean;
}

Also willDrop and didDrop maybe?
