More docs updates

Just some quick notes that I took while getting up to speed with the new version.

I can call 

```clojure
(org.jsoup.Jsoup/parse "foo" "UTF-8")
```

just fine in a REPL in the project, but I get

```clojure
(html->text (:body (first (inbox 1)) ))

IllegalArgumentException No matching method found: parse  clojure.lang.Reflector.invokeMatchingMethod (Reflector.java:80)
```

when trying to use `html->text`. Any clues as to how I can get around this / fix this? Thanks in advance!
