Code from tmary: use mrjob instead of jydoop.
Make jobs always use Saturday a week ago as their "last" date. Report on errors, errors counts, and notInitialized rates. Figure the last appInfo.appinfo and appInfo.update day separately.
Re-add output formatting to the mrjob implementation.
Merge branch 'errorcollection' into mrjob

Conflicts:
	jydoop/aggregate-collection.py
More betterness.
Merge branch 'master' of github.com:bsmedberg/fhr-toolbox into aggregate-processor
