Fallback doors.register_door() code.

This function maps doors.register_door to the new API as far as reasonable. We can't map the texture, so we fall back to a default texture. An error message is printed if mod writers did not provide the needed new tiles field for the door. The created doors are functional and a full replacement. Old doors are replaced with the new ones through an ABM.
