What is new?

• 38 new objects - mostly outdoor props like trees, bushes, rocks, and more
• New type of floor - outside floor - with new 8 materials like dirt, grass, sand, and more
• New material for regular floor - metallic - for vents

I also fixed a lot of problems with the map editor(took most of my time).
Please let me know if you find any problem or if you have a suggestion for me!
