Scribd is the worst

Querying Scribd's API for an issue thumbnail is routinely taking up to 60 seconds, causing
Pingdom to think the website's crashed. I've verified this using CI's output_profiler and
benchmark points. Until I find a way to either make our call to them asynchronous (move it into JS?)
or send them some kind of auth to stop them from trottling out API requests, I'm capping the max
time we'll wait on them to 3sec.
