tradition_himalayan_settlers MaAs

[zumbak04]

Describe your suggestion in full detail below: tradition_himalayan_settlers should be remade to give grummle MaAs, not vanilla ones.

This was adapted in db26e6f12e0f2f518918c55c7ccd0bd85858c787 of #936 . LMK if anything should be tweaked?

Maybe a new image for the MaA tab.
