500 error on catalogue submit

[blahah]

After changes made to the API today, I now get a 500 error when submitting to the catalogue. This is a new error because the submission code and data are the same as yesterday.

Example submitted data:

In vitro interferon beta treatment led to a robust upregulation of ILT3 and ILT4 on monocytes, and dihydroxyvitamin D3 increased expression of ILT3 but not ILT4. ILT3 was abundant in demyelinating lesions in postmortem brain, and expression on monocytes in the cerebrospinal fluid was higher than in peripheral blood, suggesting that the central nervous system milieu induces ILT3, or that ILT3 positive monocytes preferentially enter the brain. Our data are consistent with involvement of ILT3 and ILT4 in the modulation of immune responsiveness in multiple sclerosis by both interferon and vitamin D.</p>",

This was due to a missed failing in the date parsing. It has now been set to specifically allow our usual date format yyyy-MM-dd mmss OR date_optional_time which should handle 2014-12-31T22:00:00+00:00. Additional date formats could be added back in if necessary, see list at http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-date-format.html
