Julius: Display workers needed in fountains and missions

[LePatator]

The fountains and the missions consume workers but it is not displayed in their description panel.

I fixed it, now the workers counter is displayed like in the other buildings.

My fix is on a local branch. If you want i can give it to you, but for now i can't push it to make a pull request (err 403).

I like this, but since fountains and mission posts don't need to spawn citizens, could you get rid of the message "poor access to workers"?

[LePatator]

Ok, i removed this messages. I left the one displayed when there is nobody in the city because it still makes sense.

[crudelios]

I think you can keep the "too few people alocated by the labor advisor", as it also makes sense to keep :+1:

[LePatator]

Ok I did it
