Add Titan map with random spawn nations - along new Cosmic map category (#4183)

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:
