Reaver Titan Alternate Body

Been patiently building Lexgen's awesome Reaver as he gets the bits done, but have been making a few mods to the main body and head to add detail and change the size a bit. also modified the foot to be the correct size and made the hole smaller, which may not be as accurate, but seems to work better for me.

- Body reworked into one piece, armour built onto it and added detail. Also lengthened by a few inches.
- Head made a bit pointier at the front
- Carapace made from scratch to fit new bo
