Title: Social most popular

Tests displaying a most popular to infrequent users containing content which has been most highly referred from social media. (See shot below)

Server-side:
*Adds a social-referrals call to ophan
*Adds an agent to retrieve content from ophan hourly
*Adds a socially referred content endpoint

JS:
* Extends history API to provide ( crude ) session count over time
* For the test variant, displays the socially referred content to the user and hides the usual most-popular component
