jsonalchemy: enhance extension parser behavior

* One extension could be either a importable string pointing to a class
  object or a function call that returns a class object.

* The extensions are now listed as quoted strings, either single quotes
  or double quotes due to some limitations of pyparsing.

records: bibupload timestamp fix

* Fixes an issue causing revision verifier to reject uploads. When
  bibupload inserts/updates records it sets hstRECORD.job_date=t1 and
  bibfmt.last_updated=t1 and bibrec.modification_date=t2
  (with t2 > t1). This is intended behavior in master (see #1431).

  Revision verifier checks 005 on upload against hstRECORD.job_date
  (i.e. t1). Records model was getting modification_date/005 from
  bibrec.modification_date (i.e. t2).

  Thus getting a record and trying to reupload it would get rejected,
  since the XML would have t2 in 005, which revision verifier would
  compares against t1 from hstRECORD.

  Modification date ought to be taken from bibrec.modification_date
  and all three timestamps ought to be the same. Thus below is a hack,
  that ought to be fixed in bibupload instead. Unfortunately so much
  other code is might rely on the current behavior that it's hard
  to change.
