Bandwidth Monitorying - specify IN & OUT data transfer, instead of lumping them together

Webhosting companies and people colocating their servers at the data centre will be interested to know specifically how much IN and OUT data have been transferred.

The current Bandwidth Monitoring (> Webmin] Networking] Bandwidth Monitoring) shows the total sum of IN and OUT data transfer.

It will be very very useful to show the IN amount and OUT amount separately. In some countries, only INCOMING data transfer is billed (OUTGOING is free).

By the way, I can confirm that the bandwidth monitoring statistics are accurate. I cross-checked the numbers with my colocation web host’s monitoring system and they matched.
