* gtk/TreeNode.cs (AddNode): add an overload that takes a position

Browse Source 
* gtk/NodeStore.cs (AddNode): likewise
	(AddNode, child_added_cb): when adding a node, recursively connect
	to the node signals on its children
	(RemoveNode, child_deleted_cb): when removing a node, recursively
	remove its children from node_hash.
