Hello,

I've updated the game to address some issues and add in additional features:

0.91 -> 0.911
- Changed traffic system (for cars) to properly spawn cars from road nodes rather than from a hidden position under buildings. This way, vehicles can be pooled and reused when needed. Traffic will now appear more regularly, as opposed to roads looking empty when panning to a new area. This system is also more performant. I've also made traffic more dense. There are still a few issues with vehicles sometimes losing their way.
- Added being able to paint additional blocks.
- Improved mapping of paint on blocks to make collision detection during painting better.

- Fixed issue with painting certain blocks (due to a rounding error in a vector).
- Fixed part of text missing in tooltip when placing buildings.
- Fixed commercial buildings being locked in "Basic city planning" tutorial.
- Fixed tutorialwindow sometimes not closing.
- Fixed there being a few missing blocks in the tourism tutorial.
- Fixed being able to destroy special blocks even when buildings were placed on top.
