Render Previewed citations within break seperated divs.

 * Allow preview to persist, so refreshing the page doesn't destory the preview.
 * Removed superfluous data for returning to the previous page, now using
   javascript.

OnTime Ticket: 1100

Identified Problem:
 Both RTF and PDF previews show multiple citations as one big chunk of text, not
 separate and in the correct citation format (NLM, APA, etc...)  Happens with
 all formats.
No longer pass option argument to db_delete().

After enabling RoMEO lookups in the admin panel and then navigating to a
citation I see this debug message:

modified xpaths, updated the admin form, fixed and added elements

After working with the DOI importer, here are some bits that I thought
should be updated. In citeproc/includes/converter.inc I changed the
xpaths for //originInfo/date*. I don't think that will break anything
and may catch edge cases. I changed some text on the admin form and
provided examples. In doi_importer I fixed an element and added genre
and dateIssued. Tested on my local VM.
