0.0.4 Cabinet spline early version

Got a basic working version of the cabinet spline system up. Unfortunately, it generates an unacceptable amount of draw calls (approximately 13k for 10 cabinets and doors) so I have to get that under control before I make progress on anything else. The corner cabinet front edge on the angled face cabinet is incorrect, as well as the door positioning.

Added a baseboard option for the moulding spline. I'll probably add a custom input option as well as a chair rail in the next update.
