Colony designer (saved queues)

**What do you want to see?**
The ability to create "colony designs" which are plans for facility (and unit or even shiip?) construction on a colony independent of the number of facility slots available.

**How would it help players?**
Less micromanagement!

**Alternatives**
AI?

**Screenshots and mockups**
SE4 had a saved queue feature but it was useless because it was just a list of facilities to build so you needed to duplicate all of your saved queues for every single planet size!

**Things to consider**
See also #286 which is where this idea originated.
