New Features: * Added --cc and --bcc options * Numerous TLS debugging and verification improvements * Debug output contains whether a client cert was requested and whether one was sent * Add new options --tls-verify-ca and --tls-verify-host to differentiate between types of certificate verification (--tls-verify does both) * Add --tls-target option to allow setting of hostname to be used in hostname verification. This is useful in some inet debugging situations and required to do hostname verification with --socket or --pipe * Add --tls-chain (#60, initial implementation by Wolfgang Karall-Ahlborn) * Add --tls-get-peer-chain option (analogous to --tls-get-peer-cert, #73) * Certificate debug now includes all client and peer certs, it a chain was used (#73) * Certificate debug now includes notAfter, commonName, and subjectAltName

Notable Changes: * --output-file, --output-file-stderr, and --output-file-stdout now truncate the specified file if it already exists * Documentation improvements * Extensive test harness improvements * Add new stop-point XCLIENT-HELO to address lack of specificity when mixing XCLIENT usage with the HELO stop-point * Add new stop-point PROXY * Use IO::Socket::IP by default. Will still use IO::Socket::INET/INET6 to cover transition, but this is deprecated and will be removed in the future (#43) * TLS session debug information is now printed even if we decide not to continue the session (eg for failed verification) * Previously-deprecated functionality to allow some options to be either a filename or a literal string has been removed. Using the '@' sigil is now the only was to specify file contents * Previously-deprecated -g option removed

Notable Bugs Fixed: * TLS certificate verification did not always work. It should now
