City update public testing

Hello respected community!

Today, I've updated EXPERIMENTAL branch with the City update!

Feel free to switch to public experimental branch and let me know in case of any issue. I will be adding more content and fixing bugs meantime, so we can finally release City update to public branch soon.

Just to sum all news up, here is the list:

• You are now able to affect cities, encourage them to grow and help local ​representatives with urban plans. With your care, cities can become really satisfied and beautiful metropolises, where everyone wants to live.
  
• To achieve this, you will be shaping cities by placing city upgrades, laying roads and deciding where city should grow having more needs satisfied or where to restrict the urban development in order to protect new inhabitants from pollution of industrial areas.
  

• 50+ buildings for your towns (different levels of residential buildings, decoration tiles, functional upgrade buildings)
  
• New mechanics for cities: Zones around city upgrades. Including new overlay, icons, tutorial
  
• Each residential building has 3-4 different levels based on the combination of zones present at the building location.
  
• Different buildings appearance also through ages
  
• Added sidewalks within some city zones helping you understand where are advanced parts of your city located
  
• City now has a city square (with several levels based on city size)
  
• Added city decoration buildings
  
• New city generator able to use bridges, tunnels, rotate building towards the street or modify terrain
  

• Added more buildings color variations (8 -> 16)
  
• Rail type upgrade now possible also by drag & drop whole area
  
• Fixed Town size counter. Now only residential buildings are taken into consideration
  
• Improved no-shadow rendering (mostly shading trees)
  
• Added deferred decals shader (used for crosswalks now)
  
• Windows properly align to the empty space as close as possible to prefered position when openned
  
• Added Ramp terrain tool
  
• Fixed crash when close window while placing industry upgrade
  
• Added blinking UI highlighted items now use an arrow to make them more visible
  
• Added town message when unable to grow, also do not reset counters, only freeze them
  
• Fixed electricity overlay and electricity distribution
  

Hope you will like it! Once this update is uploaded to public branch, I will switch back to multiplayer to finally reach MP first alpha stage. Wish me luck :)

Best regards,
Jan
