Alpha 0.7 - Tree of Wisdom

This update features a major progression & UI overhaul.

Major changes include:

• Happiness is now calculated based on household average, no longer scaling inversely with population.
• All buildings now cost an increasing amount of wisdom, which comes from markets selling goods to nearby households.
• Old tutorials and wisdom progression have now been replaced with the quest system, which features a combination of main quests for unlocking buildings, and random timed quests for bonus wisdom.

Many, many other changes not listed.
