[ui] Center pasted nodes in GraphEditor when it does not contain the mouse

Browse source 
When using the Edit > Paste menu, or when pressing Ctrl+V while the Graph
Editor has the focus but the mouse is not contained in it, there is no
current mouse position in the GraphEditor so the position that is provided
to the "pasteNodes" function is the last known mouse position, which is
oftentimes on the border of the GraphEditor.

This commit automatically sets the mouse's position to the center of
the GraphEditor, and "builds" the zone containing the pasted nodes around
it.
