Basic Combat and Polish

Somewhat major update

• Tweaked player rotation speed
• Changed weapon collision from sword to Area of effect slash VFX (more consistent hit detection)
• Added health functionality with different enemy weight types on knockback
• Fixed a bug where you couldn't immediately shield in between attack animations (shown in video) and after dodging

A bug still exists where the damage numbers appear under the HP bar. Still unsure on how to fix this as my Healthbar implementation requires Overlay canvas.
