create guiApp.pasteNodes(optional group) python function (#674)

* create GuiApp.pasteNodes() python function This function paste the nodes in the clipboard. It will be used to reconnect the pasted nodes to the previously selected node as Nuke does. (good time saver) Known limitation: the nodes are pasted in a very random place probably related to cursor position. Improvements to be done: ability to paste inside a group
