Bonus Puzzle #1: Super Defender Bot

Today's update adds our first weekly bonus puzzle, SUPER DEFENDER BOT!

"Taking note of Defender Bot's popularity, Matsuzawa released the Super Defender Bot in 1987. It added shoulder-mounted cannons and button-activated sound effects, testing the patience of parents across the world!"

Also included in this update:

• Added a hotkey for selecting all the instructions in a solution (Ctrl+Shift+A).
  
• Added a new tutorial to the "camcorder" puzzle that teaches about remnants.
  
• Added a hidden config file setting for overriding the GIF output directory.
  
• Removed a joke from the end of the credits that was evidently too confusing.
