Improve the 3D editor selection box appearance

Browse source 
- Draw two boxes slightly offset from each other to give the illustion
  of a thicker outline.
- Decrease the offset compared to the 3D node's AABB to give a more
  accurate representation of its size.
- Make the box fully visible instead of only displaying the corners.
- Draw a x-ray version of the box that's more translucent, but visible
  through walls. This helps make the box more visible while still
  having a sense of depth.
- Use an orange color similar to the 2D editor.
