Pony Shipping Machine V0.3

For the second update to Pony Ship Machine, it steps up the game with a fair bit more content than the last one.

• 6 new characters: The Background 6!
  • Derpy
  • Dr Hooves
  • Lyra
  • Bon Bon
  • Octavia
  • Vinyl
• The 'View Character List' button now turns turquoise when the mouse is over it.

I intend for future updates to continue to bring in more characters at a time.
