Mod: UnitGen - Random nations with procedural sprites!

[elmokki]

Today I "fixed" nation naming, ie made four consonants in a row and three same letters in a row impossible.

I also worked on militia/start unit selection, which is working fairly well right now, but we'll see how much work it'll need once I get to trimming nation rosters to manageable sizes, which'll be soon.

And of course as always tweaked item data. Also added Chakrams (actually got a graphic) and Sticks and stones (no graphic)

There's a 19th of February version up. I know the bonus weapons give names to units far too often and that crossbows/shortbows/chakrams as seocndary weapons should be rarer. This'll get fixed eventually.
