Heightfield Merge - Revision history

Redmaw: Added descriptions to Merge modes. Replaced example images with versions showing progression of Mix amount 0 - 1. Replaced plasma noise image example with terrain example image.

Added descriptions to Merge modes. Replaced example images with versions showing progression of Mix amount 0 - 1. Replaced plasma noise image example with terrain example image.

Redmaw: Added descriptions and example image for all settings. Still need descriptions and math for Merge mode options.
