Post-jam update: New level, Iambic keyer mode

I made an update to the game, now that the game jam is over:

• Added a second level, Intergalactic Bliss (Trance Mix)
  • This level is faster and is an alphabet drill, to help you remember the alphabets and learn to tap faster.
• Iambic keyer mode
  • This mode adds "." and "-" buttons to the game.
  • Holding down the "." button sends a continuous stream of dits.
  • Holding down the "-" button sends a continuous stream of dahs.
  • Holding down both buttons sends alternating dits and dahs signals.
  • Keyboard: Use ArrowLeft for "." and ArrowRight for "-".
• The score is now highlighted after the level ends.
