Create Empty String Constant from String-Typed Tunnel

[Mr._Jim]

When I'm explicitly defining an empty string as the value of an output tunnel, I prefer the empty string constant for instant readability.

It would be useful to be able to create one from the context menu instead of using quick drop or the palette.

If you vote for or like my idea, please vote for Jim Kring's idea first, because the implementation of his idea would eliminate the need for this one. (Yes, shameless plug on my part)
