Removed old iPing application.

New apps added:
iping-client: ping client that provides statistics regarding
              the rtt and the losses.
              It allows to configure the ping interval,
              the interest lifetime, the ttl and the name.
iping-server: simple server replying to icnet-ping-client.
              It allows to configure the reply size and the name.
