"Upgrade Facilities" button might be improved.

E.g. I have just researched IntelligenceIII facilities, and if I press "Upgrade Facilities", all planets with default construction rate (2000) now take 2 turns to build it. It is better to fill planet with Intel-2 facilities and then upgrade them to level 3. So I must go to planet construction window and manually change the queques back.

It would be nice to have one more button, which upgrades facilities only if the newer facility takes the same time to build as the obsolete one.
