Environments Powder Room

I would like to give a huge thank you to @Nayris for giving me advice on how to improve shadowing for this resource, as well as for implementing real-time reflections for the mirrors. I would also like to thank @kakianl for requesting the doors as separate objects.

Version 6 now makes the doors as separate objects that can be added to the updated restroom, which is now labelled as "powder room 2." Demo scene 2 in included as a way to quickly view the new restroom. Additionally, a subscene is provided, which will enable the room and preset doors to be quickly added to new scenes.
