update v10.7

The "Metropolis" update serie will include tons of new buildings and elements for your city,  with the goal to supply a complete and realistic city tileset 

let's start with updating the street and sidewalk tilesets with many new round corners and new ways to personalize your city from the ground, literally

- Added many new modular tiles to the street tileset
- Added 4 huge round corners that can also be used as a traffic circle
- Added the "City Builder" file, that will include everything to build the backbone of your city without having to scroll through the big tilset

See you and happy game-making! :)
