#2 0.2.1: statsfile not correct when master works as selfclient

[Michael Renzmann]

The HTML file that is specified in the "statsfile"
configuration directive isn't filled with proper
information when the Master works in selfclient-mode.
The page itself is written every 10 seconds, but it
always shows that no packets are transported at all. It
does not matter if there is locally generated traffic
(e.g. pings from the master to one of the clients) or
forwarded traffic (traffic that uses the master as
router on its way to one of the clients).

When changing the configuration to the "normal" client
mode (only using "clientmode 1" and "masterip
<ip_of_master>" instead of "selfclient 1") the file is
updated correctly.
