Early Access Patch 4

Hi everyone. It's update time again, and we have a few fixes and a small feature improvement:

• The hide-plane region now always includes the camera. Things should no longer appear between the camera and the camera look-at-point when they should be hidden by the hide-plane.
  
• We've fixed the knob controlling the sun to have the height of the day be upwards.
  
• We have fixed some bugs in delete and undo that were causing corruption of parts of boards.
  
• A bug in the hide-plane has been fixed, so it now interacts correctly with un-deleted things.
  
• The range of Atmosphere fog has been expanded, allowing for less and more fog.
  

See you later in the week with more fixes!
