[APPROVED] [BUR] Headband

BUR #1988 has been approved by @NWF_Renim.

create implication black_headband -> headband
create implication blue_headband -> headband
create implication green_headband -> headband
create implication red_headband -> headband
create implication white_headband -> headband

Reason: Since headbands are not headwear as per topic #16003, the colored variants should have implications to the base tag.

Those in this BUR are all those that have at least 50 or more posts.

There are currently 553 misses, i.e. posts with a COLOR_headband tag but not the headband tag.
