Purple tier buildings

Fixes #805

Not sure, should any of these recipes be moved to Purple science? Currently all stay at blue.

Hi.

General question: is there automatic test which checks if there is no "blocker in progress"? In other words: it will fail if player is unable to reach lets say "space science" starting from scratch.

Lets say that some green science requires some ingredient X. Then some change in code is introduced that makes ingredient X not possible to craft. This means player will not be able to craft green science, so he cannot reach some techs which lead to "space science". Will we know about it?

There is a test that will do some of this. #809

The test has limitations

• It's not currently checking for prerequisites for buildings
  • Recipes for buildings are deliberately excluded as Angel's doesn't generally add prerequisites for buildings
  • If we do add prerequisites for building recipes, this exclusion could easily be removed
• It doesn't check if there is a machine available that can craft the recipe
  • This probably should be added to the test
