    This script does the following:
    - Adds a list of links to each hiding place under the Kacheek Seek image
    - Fixes all locations that broke because of https, IF you play in a single tab (don't open hiding spots in new tabs)
    - Allows you to select hiding spots by pressing their respective number key (numbers row or NumPad)
      - Number 10 is 0
      - The Shift key adds 10 to the number you're pressing (Shift + 1 = 11)
    - Allows you to return to the hiding spot list by pressing any key in the numeric row or NumPad
    - Allows you to open the next challenge by pressing Shift in addition to any key in the numeric row or NumPad
