* Fixed layout and styles of the author record page

  direct links to each of the authors publication and a better search
  query for all the author's publications

  the results are links to the records they represent
Bibformat: Links to public resources of authors

* Created a bibcheck task to retrieve the links from the viaf
  api if the author record has a viaf id control number

* Created some useful functions for viaf querying in the
  miscutil module

* Added a section to the authors' record layout that presents
  the links to available public resources (based on the
  control numbers of the author's record) alongside their
  identifying icons.
