Updated annual reviews author-date style

Removed forced sentence case for titles, per new CSL standards. Updated style per current author guidelines: book title capitalization and volume labeling, removed number-of-pages, added URL for online magazine and newspaper articles, fixed editor abbreviation.
The is-numeric test works. A page value "In press" renders as "... . In press" when inserted, whereas a page value of "1-10" renders as "... , pp. 1-10". As @adam3smith points out, the test makes roman numerals render incorrectly, but until a more permanent "In press" checkbox field is available, I think this is the most appropriate method.
