NRE fix when generating new map

Added a mod option to turn off the Natural Light Overlay button in the button right corner, should you never use it.

- NRE fix when clicking on incomplete window.
- Code and mod options related to beauty transmission (outdoor beauty being considered for window beauty) has been temporarily removed as it does not appear to be working. If I can get it working again it'll make a comeback.

Made the windows paintable in 1.4

1.4 support

NRE protection for when the graphic is fetched

Attempts to fix the seam visual glitch that can sometimes appear on the 1x1 windows at certain camera positions.

NRE fix related to modded races, which may help with RoMM and Misc robots.

Fixes a rare bug that could happen when there are no maps (caravan only)

Second attempt at previous upload.
