AI Pathfinder

• Replaced the tag ai with ai.pathfinding
• Added some scoreboards that start with prefix ai.base (ai.baseMovementSpeed, ai.baseJumpStrength, ai.baseSprintSpeed etc..)

To add store custom value that the AI can use, set the AI's score for these scoreboards. Setting these scores is optional, and if unset, they'll fallback to base values stored in ai.Values (which are also modifyable and don't reset every /reload)
