Implementing the "clone building under cursor" functionality

^{Originally posted by ravi-donepudi January 16, 2024} My favorite quality of life improvement that Julius/Augustus adds is the "clone building under cursor" functionality. I.e. if you hover over a building and press q (or the appropriate chosen hotkey) it picks the building and lets you build it rather than having to go to the menu and pick.

I have downloaded the latest build of Akhenaten and it appears this feature is not implemented yet. Could someone please suggest how one would go about implementing such a feature? I am happy to try and help implement this feature so that it can be included in an upcoming release. Thank you! :)
