Instead of just using Mbit/s or Mbyte/s to show the speed, we can use Kbit/s or Kbyte/s for slow connections and Gbit/s or Gbyte/s for fast connections.

- added "humanized" function which converts big number to kilo, mega, giga equivalent etc.
- added "--no-human" parameter which shows the speed using just bytes or bits
- when "--no-human" parameter isn't used, we shod the humanized version of speed. otherwise we show just plain bits or bytes (which will be more usable by machines)
