Gameplay and balance

- Moods and Whims:
- your goblins mood will evolve, from "Brooding" to "Cheerful", depending on your actions. The mood will provide a few small bonuses, and goblins in bad mood are more likely to activate their defects.
- goblins in good mood may sometimes become "Obsessed", triggering a mini quest you can complete to keep the gob happy (and get rewarded by a small but permanent bonus)
- Goblins wages:
- to better balance the economy, your goblins will ask some wages whenever you rest; and will get unhappy if not paid. (Note: you can disactivate the wages at the start of the campaign if )
- Limited time quests:
- random generated quests have a maximum time to complete, after which they get cancelled (this can be disactivated too)
- Smoother difficulty:
In previous version, the difficulty of quests was scaled to the player but independent from the kingdom, while the difficulty of world and dungeon mobs was only defined by their location.
This lead to sometimes weird situations, with a to high contrast between 'quest' and 'normal' mobs.
Now, the quests scale with both the player and the kingdom; while world mob are slightly scaled with the player (slightly: first kingdoms will still feel easy when coming back in late game; just not as trivially easy as it was.
- Campaign options: at campaign creation, you can turn off goblin wages and limited time for quest. I believe the game is better balanced with these options activated, but some players told me they would prefer not have these. So, your choice!

- Skills rework: 3 skills were giving the same "swap" perk. Now instead, sprint gives "sprint" order, and dodge gives access to "enemy swap"

Alchemy: recipes may be given as quest recompense
night vision reworked
increased (actually fix) enemy mobs view range, making them a bit more agressive
lower random gobs joining event rate
