Update v1.01

Made several changes and additions to start turning this pack into more of a general-purpose town-themed pack rather than just houses. The next update will have even more props and textures!

• More than doubled the number of meshes! Now with several house props, some stylized trees, simple road modules, and a few other random objects.
• Made minor improvements to the roof pieces.
• Improved the materials to better import into Godot Engine. I haven't tested this with other engines yet but the materials should import correctly into Unity and Unreal.
• Other small adjustments to improve the overall quality.

Any feedback is appreciated, including if you have ideas for anything you think should be added!
