The new ResourceListModel implements a ResourceModel to be used with QListView & friends. It provides all items of the given ResourceDB as a flat unsorted list. It'll be mainly used for the upcoming QuickLoadDialog. ResourceListModel features an internal lookup table, resulting in very good performance when filtering (even with thousands of items).
