Content update - House and signs

Hi guys, new content available!

This time I added a new bigger house (with colour variations), and 6 more sign types (arrows, skull, shield, leaf, book, magic). Hopefully now you'll have more options in creating your towns :)

Also, I included the Townsfolk character pack to the NPCs folder, in case you haven't seen that.

Thanks so much for all your support, it allows me to keep working on this.

Happy holidays~
