Simplify using physics in games

Problem

Currently the Collision and Physics treat all bodies the same way. However, for optimization and ease of use we want to consider different types of Collision Objects, particularly trigger areas and physics bodies, and have an easy way of creating each of these

Design

We propose this separation:

Collisions Plugin:

• Remove transform from Collider #1429
• Rename Collider component to ColliderAABB and make it private #1428
• Create a XCollisionShapeBundle for each shape #1430
• Add TriggerArea #1246
• Add PhysicsBody #1431
• Create TriggerAreaBundle (adds TriggerArea, CollisionLayer, CollisionMask)
• Create PhysicsBodyBundle (adds PhysicsBody, CollisionLayer, CollisionMask)

Physics Plugin:

• Create KinematicBodyBundle #1432
• Implement Static Bodies #1253

Additionally:

• Make AccumulatedCorrection private

Make sure to move all stuff which isn't meant to be used by the game dev to the src/ directory - not sure if AccumulatedCorrection is the only thing remaining
