update readme (PROGRAESS) and remove unused async dep from random.js
some progress with search
search works

its slow because it does at least two http requests: one or more to collect ID numbers, and another to get JSON objects for each title by ID

we could collect most of the information by just scraping the DOM with cheerio, but not all (i dont think?)

this way we get the same exact behavior from search as from the random and latest methods
