Discord bot reacts to D&D but not DnD

[BNAndras]

Cross-post from Discord that I still need to follow up on.

The Discord bot gives the D track reaction to 'D&D' but not 'DnD'. Isaac's suggestion was to tweak the word boundary check to not include '&'. Then D&D should get parsed as 'D&D' not 'D','&', and 'D' so no D track reaction is added.
