Added menu item allowing the user to copy 'Office in New York' image to their clipboard

I’ve been doing a lot of crazy stuff between trying to figure out how
events work, trying to use if statements in different places, and all
kinds of other shenanigans. I’ve finally decided to simply allow the
user to copy the image to their clipboard using the edit menu (or
command + c, of course) — But only when the ‘Office in New York’ window
is selected.

I’m going to sleep for the night because I’ve coded myself out!
