side cape vs half capelet

BUR #50611 is pending approval.

create alias half_cape -> side_cape
create alias half_capelet -> side_capelet
create alias single-shoulder_capelet -> side_capelet

Half capelet is the capelet equivalent of side cape. Name and alias for consistency and because the name side cape is hard to find.

BUR #50613 is pending approval.

create alias side_cape -> half_cape
create alias side_capelet -> half_capelet
create alias single-shoulder_capelet -> half_capelet

Reverse alias option because the current name is a bit counterintuitive, most of our tags use "half" instead of "side", like half mask, half-skirt, half-jacket.
