v 1.2.0.11

As I'm no longer actively working on the game, I thought it would be nice to do some cleanup and address a few things to just overall make it a nicer experience.

So towards that end I have:
- Made the city generation a little faster to lessen the performance impact
- Removed some online multiplayer code that never came to fruition but was slowing everyone down by just existing
- Updated to Unity 2021.1.3f

And, to make it fair, here are the patch notes for some previous versions that I may have forgotten to add on here before dramatically exiting:

v1.2.0.10

Fixed issue with score not uploading correctly for seed 5555555555

v1.2.0.9

Fixed a bug where it would cause the game to spam an error regarding Unity Event System
