Merge pull request #80 from 18F/coveralls

Trying to add coveralls.io reporting
1. added processing time stats to both agency and offices to increase coverage for offices that have the same name as thier agency
2. updated the mapping key for both foia.gov/data and foia contacts. This will help query info from the foia contacts xls when we need it
3. minor changes to the processing time scraper to work with new mapping key
Merge branch 'master' of github.com:18F/foia into extract_contacts
