Detonation combos, better loading screen, better wall texture

Detonations

Added combo logic, animations and sound effects for detonations. A status effect can sometimes be detonated by another ability, which results in approximately 2.5x the DPS of the original ability which granted the status effect. Current combos are:

• Fire detonates Burning (from another ability)

• Psychic detonates Disoriented

• Bludgeoning detonates Frozen

Loading screen

Added an aesthetic loading screen with tips for the game, using images from the generated game world as the background.

Wall textures

Implemented AI-generated wall textures in place of the tree stump

Misc

• Added frozen status effect

• Added healing animation

• Nerfed status effect level for consumables/events to avoid being one-shotted by being burned

• Fixed bug in quest display when quest giver was in a sublocation

• Added option to change save file location.
