Adding Sensor Component only works for Dynamic Rigid Bodies

> Sensor colliders on the other end don't generate contacts: they only generate intersection events when one sensor collider and another collider start/stop touching. Sensor colliders are generally used to detect when something enters an area.

This sentence is misleading, it suggests that I can simply just add the Sensor component and I the entity will not be collidable. However this will only be the case if the entity also contains a ridgid body component.

The squares around this player are child components that are made up like this.

```rust
builder
.spawn((
Sensor {},
Collider::cuboid(10., 10.),
Transform::from_xyz(20., 0., 0.),
));

```

These should not be collidable, but they are - they are only Sensor components when the parent entity is a dynamic component. I might be missing something here though :)
