Catalogue text fix for the Keystone-Style and Prairie Post and Lintel Knockoff arches, which had their names and descriptions swapped. This swaps them back.
“A keystone is the wedge-shaped stone piece at the apex of a masonry vault or arch” (Wikipedia).
STBL override for 0x5DB76249, 0x678A2CB6, 0xF5003E96, 0xFDA97D6F, US English. No other languages included since I don’t know whether it’s wrong those too.
