Set 'java.rmi.server.hostname' property on client too

The RMI documentation (http://docs.oracle.com/javase/7/docs/technotes/guides/rmi/javarmiproperties.html)
says it is useful to set up a `java.rmi.server.hostname`
system property on a client and a server.
When the property is set up on a client, I saw that "RenewClean" threads
stopped listening to my external IP, so all client and server threads
are now only listening the loopback interface.

I also changed the way the property is set up on the server side:
before the change it was passed in jvmargs at a process launcher.
I moved this code directly to the main method of the daemon,
because it is easy to forget to set up the property,
when running the main for debug purposes.
