Advancement Rework

[TheDeathlyCow]

Resolves #144

• Updates the Frostiful advancement system to have its own page with three tracks of progression: Warmth, Armor, and Frostology.
  • The Warmth track is based around advancements that teach the player how to utilize a few heat sources (light, campfires, and sun lichen).
  • The Armor track teaches the player how to obtain fur and gives advancements for crafting fur armour and ice skates
  • The Frostology track is the main progression of the Frostologer Castle and Chillager structures, and ends with the Frost Wand, Frostologer Trims, and Frostology Cloak.
• The root advancement of this page is only revealed when the player's temperature goes below -10%.
• Some existing advancements were tweaked slightly, but all previous advancements should carry over.
• Reduced size of the frost wand effect cloud a little bit
• Brushing an animal for fur now plays an animation

TODO:

• Challenge Frostology advancement for rooting 3 creepers at once
• Unit test the new loot context types
