Antique Atlas 4

Changes:

• Update to surveyor 0.5.2, turning a few crashes into logged errors.
• Don't re-include kaleido, reducing jar size.
• optimize textures w/ oxipng (oxipng -o 6 --strip all --alpha **/*.png)
• jar size is roughly halved.
• add an extra null check for surveyor handing AA null structure types.
