We're still seeing some reports that the new PubMed isn't working, so
trigger another update for clients that failed to pull the update for

Various adjustment to make the code work, mainly:

  - Add DOI
  - Adjust textVariables (metadata names). Remove some obsolete ones.
  - Optimized the way author names are handled.

DOI: Find DOIs in links, and other improvements

Translator is currently broken and needs to be updated, though

Also add a list of electronic only journals for which we use the RIS page number

Multiples, collections, bibliography; also update tests & remove invalid 
URLs
