Fixed Netspoc now aborts on inconsistently defined area having contradictory attributes "border" and "inclusive_border" (#48). Program "export-netspoc" no longer generates cryptic name for dual stack service with missing IPv4/v6 part (#58), no longer generates empty IPv6 rule for service with "foreach" and "ipv4_only" (#57). Program "print-path" no longer panics when finding path between dual stack object and IPv6 object (#56).
