update v42.0

This will be the very last theme of Modern Exteriors.   
Ranging from different styles and shapes, each update will feature a whole new building

- Added a Japanese Suburban style House

 - See you and happy game-making! :)

The new theme is only available in the "WIP_Theme".zip until it's finished.  This way you won't have to download the whole asset to just have a couple of new sprites.
