L4D1-Style Tank

The original L4D2 tank was a tad too pink for my taste and I loved the original L4D1 tank, though the absence of hair in the second was a welcome change. And so I just decided to cross them, taking the best of both in to one.

Also added some wounds and fractures to show that hurling rocks and cars around isn't without consequence.

.VPK now included.

**Update*** - Added custom Normal (thanks CaptHammer).
