 Presently, the WordPress Importer extends WP_Importer and does a lot of
 processing steps, but in many cases errors are directly echoed or
 printf'd. This interferes with the cronjob-oriented design in #327.

 In addition to converting tasks for cron (#327), this ticket tracks
 changes pertinent to the separation of presentation from backend work.
