Shingle a7

Changes to this version include:

• Under has been removed and replaced with a small shack at the edge of mid
  
• Sniper balconies have been extended to make use of empty space
• Spawns have been made more defensible
• Health and ammo pickups have been revised
• Mid has a new coat of snow and some more uneven terrain
  
• A major entrance to lobby has been shut, I'm keeping an eye on how this changes pathing
• Spectator cameras added
• Rollback zones now slow the cart by 50%
• Handrails no longer block bullets and explosives
• More crates in warehouse
• More signage around spawn

The map has been revived and revised, hopefully all for the better! The original goals of having a less stalematey plr remain, but with a more indoor layout than before. Images will come soon.
