Updated jargroup list to also display version (if linked)
Changed server create to set msm_version if jargroup has version linked.
Fixed command_server_config to escape values
needed to properly set msm-version (i.e., minecraft/1.0.0) - the "/" was breaking the sed command.
Fixed cosmetic typo.
Added "console_property" that sets values in server.properties when set_jar is called. Goal is to be able to properly setup the server.properties for a given jar/server.
