Subject: Add IScriptModuleComms interface and region module to handle dispatch
 of script messages to region modules and sending back replies. Hook
 IScriptModuleComms.OnScriptCommand to see commands and use DispatchReply to
 reply to the script. It is recommended to pass the "id" parameter from the
 event as the "k" parameter of the reply. The script will receive the reply as
 a link message from link -1.
