Pubstwo 995

This is a partial implementation; I've only tested it for persistence of biblio data with the existing pub (#2).
I think it might be nice to move this to the model with a getter/setter.  Have the model store displayToPublicDate as a string and have the getter do new Date() and the setter do toISOString().  Not sure if this is good as it makes the getter a bit slower than normal, but worth a try maybe.
