Most of these are more changes to reflect the current UCM output. Mostly around Proved. vs. Passed 1 tests., and around UCM making less use of absolute namespaces.
The update of square no longer adds in full namespaces, so I removed that comment explaining why UCM does that.
Lastly, foldl is actually named foldLeft, but the code explaining update at the end of the tour used foldl, causing a missing definition for anyone following along in the tour (earlier the tour does have the user rename foldLeft to foldl to explain term renaming, but the tour then has them undo this change).
