Merge pull request #2 from ossapp/master

RTP Packet class
Updated git ignore
Added new RTP resizer and RTP pcap reader classes
Updated test cases for RTP.  Disabled DNS test.
Added libdnet as dependency
Added libdnet firewall wrapper.  Unfortunately this class only works on BSD.  On Linux, it only supports ipchains and not iptables.  I will provide an alternative using iptables when I get the chance.
