Added more selectors, minor bug fix

Fixed a discrepancy between Vanity Fair and Concurring Opinions. Added
selectors for Swissinfo, Latin Post, BBC, Herald Scotland, Star
Advertiser, NBC
Minor change to attribute bias tokens

Added nfarticle to work around a token weighting issue for certain
domains
Fixed reference to URI.js

After moving URI.js out of medialize folder in a previous commit, I
forgot to update this reference.
Complete rewrite of deserializeFeed

Broke apart into functions. Cleaned up some functions. The major change
is to treat atom and rss formats separately in order to avoid the
repetitive if statements that littered the prior version.
