New adaptive difficulty and more Missions

After a week of hard thinking I made up a new formula for adaptive difficulty. I posted it on the discord, maybe if they figure it out it will be adopted.  No need to wait for that though, it's here. 

It uses R relics forged; D for current difficulty, and FC fate cycle. 

Chance to increase difficulty is via a Core die, and rises with FC, falls with R and falls with current difficulty. 

In other words, difficulty won't increase at all, then only with low chance, then with high chance, and finally with low chance.

As for tutorial I put some work in the first dozen missions, for easing everyone into the game with simple, concrete goals. Much like, well... a tutorial ♥
