Add fields in the Bibliodata tab

Fields still need to be in the database and served by services.  Not
sure about order of new fields in UI either.  Added in datetimepicker
for last modified date
Naming it 'date' is technically correct because it is in a different controller, but I agree with PT, a more descriptive name would help the next developer a lot. A couple of other controller/view-pairs have used `localMyVarName` in the template and `myVarName` as the model attribute to write to in the $watch. Either localLastModifiedDate or rawLastModifiedDate seem fine to me.
