Adding New Data Protection Notice Type

This branch includes a new notice type called Data Protection for the EU Right to be Forgotten. To make searching these notices possible it was decided to add in an auto-populating of topics to each notice when it is submitted. The notice type -> topic mapping can be found in app/models/notice.rb. There were also several text edits that came out of testing. Also thrown in is the Redact Queue error fix.
