Fixes #97 for TagDiff command including a related issue for TagTest
Additional patterns were added for detection of cloud storage services, and minor improvements to regex patterns for client based TLS auth, Kerberos and SAML. The newer Metadata tags checks against the file type scanned for avoiding elimination of subsequent checks for an unaccepted match was relocated to the rulesengine to ensure valid matches were not eliminated . We will continue to add and improve rules for detection while keeping false positives a low rate.
