app: add new virtual function GimpItem::unset_removed()

Browse Source 
and implement it in GimpLayer to unset the removed flag on the layer
mask. Remove layer mask special casing from gimp_image_add_layer().
Make sure that all an item's children get their removed flag unset in
gimp_item_unset_removed().
