Add RemoteCommand 'status' command.

As DMRGateway, it reports connection status.

Command sent: "status" to port: 7642
dstar:n/a dmr:conn ysf:n/a p25:n/a nxdn:n/a fm:n/a

RemoveCommand has been slighlty modified, as using Log on a read-only filesystem simply forbids the strings to be displayed.
Another solution would be to set LogInitialisse's filePath to "/tmp/" for *nix systems.
