Ctrl+C & Ctrl+V Issue With Graph

[dyanikoglu]

Clicking on a node and doing ctrl+c & ctrl+v directly doesn't paste the copied node while the original node is still selected. It's needed to click on an empty area in graph for Ctrl+V to work.

This is because after adding add-ons copy-pasting logic slightly changed. Now when you have selected node when pasting, code is cheking if selected node can accept pasted nodes as add-ons. If not - nothing gets pasted. Potential fix for this would be to add check if pasted nodes contains as least one add-on, and only if it is true - consider previous check.
