Specter Hot Fixes

- Added the ability to add scene objects in front of the camera by holding Left Shift and clicking the element you want to add.
- Added UI button on the main toolbar for resetting Camera position.
- Camera now resets when starting a new scene or loading an existing scene.
- Made a few updates to the IK Posable Characters. The elbow's and knee's now have bending support. You can now "Dab".

Thanks!
