Products: carry the IMVU parent's image and categories

Revisions with an IMVU parent store its public info (image, category path, gender)
from IMVU's product API, looked up after registering and in a periodic pass.
Product views gain parent, image and categories; GET /products takes category and
limit. The website shows the image on cards and product pages.
