- [documentMaster] Issue #24 required reworking of how "receiveScan"
happens. It's gone to a more stable, transactional process, where each
scan receipt is noted in the database and finally at the end of the job
run work distribution takes place for all received scans
- also a few minor haml changes
Merge remote-tracking branch 'upstream/master'
