Changes: Adding possibility to specify identifier when item is recycled.

RevBy: Tomas, Stanislav

Details: Currently MWidgetRecycler uses class name as an identifier to recycle&restore
objects. Sometimes it's not very convinient. Same class may implement different layouts
and reinitialization those layouts can make performance worse. With this patch developer
could assign custom identifier for 2 and more groups of objects with same class name
and keep the performance.
