SLASH v0.11: Combat Update (omg zenkoh is that a minecraft reference!!!1!)

(The reason for this update is that I realized that swords don't shoot, guns do.)

• Added Light Slash 3 DMG, 0.6s cooldown
• Added Heavy Slash 12 DMG, Sweeping (evenly spreads damage), 1.5s cooldown
• Replaced LMB for Slash to CTRL + LMB for Slash
• Added Dynamic Music
• Added main menu music (very quiet for some reason)

 CHANGES:

• Fixed Slash's direction to face wherever it is going to
