Ruby setup with 2 network cards

[Belinda Frick]

If there is more than one network card in the ruby server, the
server sometimes replies with the incorrect network IP address
to responses from the client software.

Add the following to the ruby.ini file to ensure that Ruby always
responds with the same IP address:

[RUBY]
RUBYHOST=192.168.0.100


The server will then always respnd with the 192.168.0.100 IP address
an not use any of the other interface's IPs.
