The text is wrong, the copy and Paste are wrong

[libaineu2004]

I found a text error in one place:
https://github.com/paceholder/nodeeditor/blob/master/src/GraphicsView.cpp
line,132,_pasteAction = new QAction(QStringLiteral("Copy Selection"), this);

The correct way to write it is:
"Copy Selection" --> "Paste Selection"
