1.6 Major Update!

# - New block type, Walls!

You can now enjoy all of the glory of thin walls!, adding variety and a bit more realism to all this, enjoy recreating the Backrooms accurately now!

- Updated Every Single Bumper variant of the wallpapers

They are 3d now!, been on my mind since I added bumpers, feels good now that I got it out of the way, including the new wall variants!, all labeled correctly and should show now when you search Bumper or Backrooms.

- Updated various blocks names.

- Two updates to Chevron wallpaper

Changed it from using Bricks to Warped Planks due to an issue with walls and fences not connecting. I suggest using world edit or axiom or what have you to replace the former with the latter.

Changed its scaling to be less dramatic than the last update.

- Changed Dotted Wallpaper from using Sandstone to Mangrove Planks

(same reason and solution as Chevron)
