VPN Traffic Amount in Human Readable Format

Normally, VPN traffic amounts are registered in the amount of
bytes that have been transferred over the VPN link.  But that's
ugly, ugly for humans that is.  Most of the time people like
Kilobytes, Megabytes, and Gigabytes; not ugly Bytes.  This
modification changes that so that you get a nice way of
describing the amount of data that has been transferred over
that VPN link.
