New spawpoint and new wallpapers — Santas Basement Steam update #544960

I am unhappy with the basement and the generic store-bought assets for the house, so I did some tweaking. Santa now starts asleep as well for about 5 minutes, so you can explore the house before he becomes active. I have also done some work on the lighting and reflections, but I am not too happy with it, so it will be improved later.
