Echoes of the Dark God 0.2

Writing these mostly for myself.

• You can now use items in combat!
• You can now drag items in inventory, and also equip, remove, and switch them by dragging!
• Added a toggleable combat log! Game will remember between sessions if you chose to have it open
• Added skill trees and some more skills to choose from!
• Added more dungeon to explore after the first boss encounter
• New enemy types and new encounters in this new part of the dungeon
• New riddles/secrets!
• Added a new UI icon to toggle inventory with the mouse
• Added a few button highlights that I had forgotten to add in the previous patch
• Fixed a bug on level-up screen where the Level-text always read Level 1
• Fixed a bug where the enemy's hover effect didn't trigger if the mouse pointer was already on it when starting targeting
• While combat is in progress, you'll now always see a red crystal ball surrounded by a couple of hellhounds!
