Improvement: Rally point available for unfinished buildings

This would help when building TCs and for late game when one is spamming lots of production buildings.

Currently one has to come back to now finished buildings to set a rally point. If one forgets, one gets idle villagers or soldiers…

I for one rarely go back to my production buildings. I just use my hotkeys and produce.

I use shift [+hotkey of the production building] to select all the production buildings and train units, without ever leaving the action. I therefore never see idles until I notice I’ve an uncomfortable high number of idle villagers. Military idles often entirely go under my radar, considering there isn’t like in AoE III a button to send all of them to a certain place on the map
(see Add all military units command button, just like in AoE III)…
