PWB2 v1.0.0-beta.4

• Separated the tool animator, so only 1 is made and used across every tool (instead of having 1 per tool)
• Added aim recoil and accompanying test weapon (using aim recoil to recreate CounterStrike spray patterns)
• Started on an entity system (will be used for grenades and other prop based projectiles [however physical bullets should not be physical props)
• fixed bugs
• improved documentation and function naming
