Demo 19

I changed a lot in this demo, building off of last week's work to keep improving the first area. Here's what's new:

• added sage's hut map + sage NPC that teaches players a new skill
• added new skill Haste (boosts player evasion)
• rebalanced player stats/xp to level up
• reworked the first boss to a point I'm actually very happy with
• Player speed is much faster in general
• Walking through forests in the overworld slows you down/monsters are easier to find
• Players auto-regen health after battle
• Reworked every building map in Port Town and added NPCs to the town
