added modifier <O> to command <-E/--edit> for editing of post-processor-queue; following subcommands are supported: <+/-offset>, <T>, <B>, <D>; subcommand <D> supports deletion of queued post-jobs and active job as well; deletion of active job means the cancelling of par-check/repair or terminating of post-processing-script (including child processes of the script); updated remote-server to support new edit-subcommands in XML/JSON-RPC
