Added Server Side Module (ClientList) for display of information about groups and connected clients. Required addition of intermodule communication routines within the Group handling code to allow data to be used in ClientList module. Assorted javadoc cleanup/additions in all modified files. TODO - need to add mechanism for modules to be notified when data in other modules has been changed; ModuleManager has skeletal support for this already but it needs fleshed out. --Snowdog
