net/libnet10 expired, set the 12 dependent ports to expire 30 SEP 2014

The ports the depend on net/libnet10 should have been set to expire on
the same day as net/libnet10.  That didn't happen, so postpone the removal
of libnet10 three weeks to afford an opportunity for 12 ports to migrate
to a new libnet.

Remove indefinite articles and trailing periods from COMMENT, plus
minor COMMENT typos and surrounding whitespace fixes. Categories D-F.

Add dns/dnshijacker:

dnshijacker is a libnet/libpcap based packet sniffer & spoofer. a
versatile tool, dnshijacker supports tcpdump style filters that allow
you to specifically target victims. dns answers are forged based on
entries in a "fabrication table" or by simply forging one answer to all
requests. a print only mode is also supported, allowing one to simply
monitor dns traffic. dns hijacker is an excellent tool for network level
ad blocking / removal.
