Unsupported Trillium Sherpa Armoured Patrol Vehicle 1.2

Full list of changes:

• Decreased total file size by over 5 KB
  
• Strengthened cabin, suspension, and tires and added front crumple zone
• Added nodes for rear driveshaft and differential (it is now fixed to the rear wheel hubs and will no longer awkwardly stick out in crashes)
• Engine cannot be broken in a crash, but is still vulnerable to RPM and water damage
• 3 new colours (Matte Marsh, Matte Steel, and Obsidian)
  
• Modified many internal materials to look more rugged...
