change logging server from localhost to arbitrary ip

```
What steps will reproduce the problem?
1. install python-loggingserver
2. start server and test harness
3. go to ip address of server from workstation on port 9021

What is the expected output? What do you see instead?
The log results in FF, get 404, No Such Resource.

What version of the product are you using? On what operating system?
Twisted 10 installed from src on aix 5.3 for the server. Client is win7, ff3.

Please provide any additional information below.
I see that loggingtest.py has a key for logging_server, I do not see how to
change the address of the server itself from localhost to 192.168.1.18.
