[ui] make Nodes moves undoable

Browse source 
Handle nodes move and auto-layout on Python side by using GraphLayout and MoveNodeCommand.

* Node QML component relies on underlying core.Node object's position
* MoveNodeCommand is called after a Node has been dragged
* partial/full auto-layout for specific graph operations (Duplication, Augmentation...) are now part of those operations
* serialized position in node data allows to properly restore nodes coordinates on undo/redo
* remove all layout/node moving code from QML
