Split the gallery into sections with a divider, start the colored set

Generators now live in gen/<section>/<subject>/<action>.js; the section
folder picks where a tile shows in the gallery and isn't part of the URL.
The first 50 are in gen/bw, a dashed divider follows, then gen/color.

First colored ones: fox/sleep, pig/oink, duck/swim, whale/spout,
turtle/walk, owl/blink, crab/dance, butterfly/flutter, dino/stomp,
jellyfish/pulse.
