When creating a new blackboard variable, you can pick some engine component types but not all of them. For instance, you can create a Box Collider 2D variable, but the Box Collider (the 3D one) isn’t there.

This is a UI bug in the blackboard, only the MonoBehaviour classes are present, but not the Component one.

A workaround for now is to create the variable using the “New Rigidbody…” option from the node linkfield.

Steps to reproduce:
1. Open a BehaviorGraph 
2. Try to create a new Rigidbody blackboard variable in the Blackboard window

Actual results: 
Rigidbody and engine components types are not available in the Blackboard menu.

Expected results: 
It is possible to create BBV of component types.

Reproducible with versions: 
1.0.7
