ehancement Unity: visualize position and vectors for placement of TriggerBoxes and MeleeContext

[ghramsey]

I asked about this on discord.
It sure would be nice to visualize the x-y-z of the triggerboxes and for Android corpse traps the MeleeContext boxes.

I know you're busy with the physics stuff but when it's possible hopefully this is doable w/o too much extra work.
