Add author detail page

This replicates the view of the EOA1.5 platform with the important
exception that all information is directly queried from the
publications. There is no need to assign the author or editor a number
and use that for referencing.  Querying is done through first and last
name of author, applies even to the list of contributions which lists
authorship of chapters in other publications automatically.
