Resolves#4182
## Description:
Adds "Titan" (real moon of Saturn with methane seas) map . Uses new
random spawn nation feature by FloPinguin.
https://github.com/openfrontio/OpenFrontIO/pull/4156
Also adds new Cosmic map category. The "Other" map category has become a
wastebasket of unrelated maps, and with increasing number of maps, i
think its a good addition to have better categories for these maps.
I figured these 2 changes should go together since im adding a cosmic
map, and a cosmic category.
proof of nations spawning randomly and how the cosmic category looks in
the menu:
