Updated 43f to fix calculation of keep_through days/months/years in get_*_usages(), plus updated calculate_repository_*_usage() to be more lenient about blank lines in the output from get_*_usages() as well as correctly handling return code from get_*_usages(). Implemented test cases for daily, monthly, and annual disk usage statistics. Issue #310
Updated 43f & README.md with 0.1.4 version & change log.
