Add "Trackpad Friendly" camera control setting inspired by Blender (#431)

* Refactor: rename CADProgram to CameraSystem

* Fix buttonDownInStream always set to 0
This is problematic because the left mouse
button ID is actually 0. If no button is
pressed we should set back to undefined.

* Fix: middle mouse button ID is 1, not 3

* Add "Trackpad Friendly" camera system setting

* Allow camera configs to be lenient on first click
