Dsc 434

This request include fixes/changes requested in dsc-434.  The following code changes have been made:
- Start button for re-ocr on the job edit page has now been processed by ReprocessController reDocworksJob() 
  method.
- The saving of job details called in methods in JobsController and ReprocessController has been refactored into JobRecord saveJobDetails() method.
- Various freemarker templates changes as per dsc-434.
I think add a default value to the RequestParam and set it to empty as default so that the check will then only be an isEmpty() check.
