I've done a bit of refactoring today in this branch:
https://code.launchpad.net/~widelands-dev/widelands/bug-1348795
Check out the new ProductionSite::out_of_resources function - when that
function sends a message to the player would be the point where the AI
should do something about the building.
I don't know how the AI API works, but I guess you would either access
the message or set a flag in the production site for the I to read.
Message sender at the moment is "produce" or "mine". I don't really know
what the sender is for, so if it doesn't break anything, feel free to
change the sender as needed.
