Allow manual map building for players.

[AlexanderChernyshev]

Our model for the game to work should now be to give players points based on their code, and let them build corresponding buildings as they see fit.

We can keep auto-gen maps as a default, using whatever algorithm/clustering we have built so far. But we don't need to develop it further since we now plan to encourage players to build their own maps with their points.

This will make it easier for us not having to develop advanced calculation for map gen, and allow users results they are happier with.

• Need a button to copy code of what you built before to add to map. This is like a save file.

Plan:

1. Initial plan is to have points in a repository shared communally among contributors.
2. When manual build enabled, player taken to page with empty game
3. this with show points available for repo
4. need UI to open builder, show what buildings you can pick and grid where you can place.
