Added population of 'people to be told' into PDF

Section 8 in the app
Moved PDF config files under pdf_config dir

In order to keep them separate from the
Rails config files

For some reason, 3rd person to be told is not being
processed. Will resolve this!
Fix for people to be told
Merge pull request #120 from ministryofjustice/feature/people_to_be_told

Add people to be told
