A slight tweak to the UI

A very simple change, yet something that would serve to add clarification would be to change the current selections that appear when you try to cancel construction from the current "Ok" and "Cancel" to "Continue" and "Go back" (or something along those lines) The reason for this being that it would be a lot clearer that way, as someone who accidentally presses the cancel construction button might then press Ok instead of cancel, thinking that the button that says Ok would not cancel the action. Please make this change in order to prevent countless accidents.
