Add "toggle comment" like in atom and other text editors

Please introduce the functionality to quickly toggle comments in code editor, i.e.: Wrap comment syntax around selected text if it is not a comment yet or remove comment syntax if selected text already is a comment. In Atom this feature is called “toggle comment”.

It seems like such a basic feature that I was surprised pinegrow code editor does not have it yet. I find myself commenting and uncommenting lines of code all the time for testing purposes. Of course I could use Atom for that, but it would be really handy to have this feature also ready to use in the pinegrow code editor.
