Doaj Correction

Sorry, made a mess of this and not too clear how to separate out the issues. 

Core patch is the modification to DOAJ scraper which was leading to things not updating (the update-fields setting was set to 'open-access' not 'open_access'). 

There are also some new reports and scrapers in there but the hack for date parsing is still in. 

Not sure enough of Git procedure now to clean this up in retrospect :-/
