BUR #2280 has been approved by @evazion.

create alias fur-trimmed_hat -> fur-trimmed_headwear

Reason: Consistent with other hat -> headwear aliases

EDIT: The bulk update request #2280 (forum #163054) has been approved by @evazion.

We still need to alias all the pattern_hat tags and some other ones but I guess this is a good start.
