The COVID-19 update.

So, coronavirus happened. It kind of threw lives for both me and Demian upside down and really slowed down the development. There also haven't been any public updates in half a year now, so I thought we should finally get what we've added since last time to everyone's hands.

As usual, I'll try to keep it short, but here's a changelog since last public release:

• rivers now receive glacial melt
• waterflow is seasonal (important for wadis and seasonal rivers)
• new "satellite" map mode
• soil moisture simulation
• grass and shrubs simulation (trees and soil organics are still missing)
• completely reworked UI
• a ledger for global statistics
• an options screen (you can finally turn down the volume if you want)
• better name generation for provinces and countries
• pathfinding algorithms of all kinds for future use
• improved generation of countries
• graphical country borders
• simple technology simulation
• fixed map exports (no more unnecessary distortions around poles)
• improved permafrost soils
• sliders controlling generation of realms
• modding support for technologies and languages (as in, languages of countries in the game, not the language used in the UI)
• improved resource generation and simplified modding support for it
• categorization of map modes for easier access
• categorization of defines into categories for easier access
• defines presets
• minor bug fixes

The update also technically includes simulation of religion, cultures as well as algorithms deciding which societies are hunter gatherers, nomads of agriculturalists, but I haven't included them in the checklist because you can't really view them yet (well, you can see the last one in the "CalaDebug" map mode).

I was hoping to get pops and characters into this update, but unfortunately, with covid making my life a hell with constant coughing and fever, I ran out of time before a period of exams in my college. We will probably release another update that includes these features before the final 0.2 update.

(As a closing note and a bit of a warning, change default defines to "no vegetation" for your first run. Otherwise, you'll generate half a millennia of plant growth and that really takes a while)
