Add additional "section front" pages to NYT parser to find URLs that don't make the front page

By adding about 30 additional "section front" pages, we are able to find content which is published but which doesn't appear on the NYT front page. 

In one quick test, including these extra pages raises URL generation time from 3 seconds to 35 seconds and raises the number of distinct, pre-canonicalization URLs from 119 to 1322.

(Many generated URLs are duplicate links to the same article with different "?src" parameters; canonicalization should strip out these duplicates.)
