Updated JinTracker to have better visibility/readability + Added a version without the character images

[JinchanJ]

Changes made:

• Added a border that has that player's color around each player's container.
• Implemented automatic font and shadow color switching for better visibility/readability.

How the automatic font and shadow color switching works (also in the README):

• When the player's color is dark, the texts in the chips become white and have a dark shadow beneath it, the shadow surrounding the player's container becomes white, the color of the inner container becomes white, and the color of the player's name becomes black.
• When the player's color has medium brightness, the texts in the chips become white and have dark shadow beneath it, the color of the inner container becomes black, and the color of the player's name becomes white.
• When the player's color is bright, the texts in the chips become black and have no shadow beneath it, the color of the inner container becomes black, and the color of the player's name becomes white.

I also created a version without the character images to the sides (scoreboard_JinTrackerNoCharacter).

Thanks!

Going to close this because I think it would be efficient to combine the two folders since they use the same CSS file.
