Buttons graying out update (v1.1.1)

What changed?

Buttons that cost resources will now be grayed out if you dont have the resources for them.
This allows for better UX like in this image where the player can more easily see what they can build.

Is multiplayer still compatible?

LAN multiplayer should still be compatible between this version (v1.1.1) and the previous version (v1.1.0).
