Hectic Delivery 2 (Gull) 1.1

I decided to update the thumbnails for this due to prettier graphics, and wanted to add a little extra something. Here you go!

• Added a bonus scenario, full of Pigeons
• Renewed thumbnails

Fix time!

• Fixed headlights issue
• Fixed vehicles spawning in fences (I think? I tested this a few dozen times and it seemed all good)
• Raised spawn point a bit
• Added a new sample Lua file, useful for easy traffic setup for scenarios
