fork of 'turkopticon' by Lilly Irani and Six Silberman --
* turkopticon-async requests data from the Turkopticon servers asynchronously which improves
performance and prevents the page from locking up until the request completes
* no more flickering
* now works on the 'preview' page
* coloring via simple weighted average consistent with HIT Scraper
* additional minor refactoring
