add celebrity heights

- lists celebrity heights.

- meant as W|A replacement.

- CelebHeights.com is the canonical data source (along with wikipedia; coverages overlap but aren't directly comparable)

- tom cruise height

- useful for people who search `<x> height`

idk how to test this with DDH but it presumably works :smile:

I couldn't remember if i was supposed to include `height` in the page title or not so i just did -- i think i'm probably not supposed to and then we add `height` as a trigger for this source number and it does a remainder match?
