Suburban update

This update introduces the first content pack, Suburban, available right now and for free!
In total it contains over 40 new decorations including buildings, passengers, vehicles and animals.

Optimisations
Players with weaker PCs or very large worlds should see some nice performance improvements.
As part of this, MANY decorations have had major (hopefully invisible) reworks so if you notice anything odd about existing decorations please let me know! There are also several new tools in the options menu to improve performance even more.

Sprint
You can now hold Shift to move faster in build mode, very useful for big creations.
If you have previously made changes to key bindings you might need to open the Controls menu and manually assign Sprint to a key of your choice.

Passenger changes
The "Single" and "Group" system for passengers in the toy box has been replaced.
There is now one option per passenger style. Placing a passenger with a key press will put down one just like the "Single" used to, and holding the key will quickly place up to 30 passengers in a circle.
