productizing: version update
adds a sendCommand() method to TCPSocket, similar to SCTPSocket.
improved REDDropper, in order to provide a functionality similar to
the old REDQueue. It is not explicitly needed for NetPerfMeter usage, but the
change from REDQueue to REDDropper removed some functionality
adds the NetPerfMeter application model and an example under
examples/netperfmeter. The example uses SCTP, but this could simply be changed
by replacing "SCTP" with "TCP" in the .ini file.

Note, that NetPerfMeter provides SCTP, TCP and UDP support, i.e. it is at the
same time a TCP, SCTP and UDP application.
