Subject: [PATCH] Pass command to DoCommand through global command queue
Rather than passing the command to process as a parameter to DoCommand,
we now append it to a global 'command queue', from which DoCommand() then
reads the first line. This in preparation for letting the engine thread
handle the difficult commands.
