A Few Reworks

I've added a few alternate versions of Red Vulcan and Sapphire Giant. I completely retextured Sapphire Giant in a more realistic style, and put it into Unreal Engine 4. I also put Red Vulcan into a more brightly lit environment. A hi-res render of that is in the gallery. I also added a Videos section, as a child page to the Gallery. There are currently two postings there.
