test build 3085

I've tested it a lot in noggit but not ingame so please be careful and backup your maps before using it.

Main changes:

• some minor bug fixes
• Varen's multi object rotation tool
• some rendering performance improvements
• auto focus editing window when the cursor is entering it
• fixed some texturing issues (ex: https://www.youtube.com/watch?v=cCoSve4mS2w)
