Allow alternate bw limits in k/m/g bits

Currently relay bw limits can be set in 10n based bytes per seconds. Standard in ISP industry is to use 2n bits per second.

Add alternative measurement units instead of KB/GB/MB defined:

1 Mbit = 1024*1024/8 bytes/sec 1 Kbit = 1024/8 bytes/sec 1 Gbit = (1024^3^) /8 bytes/sec

It will make bandwidth limit settings much easier to match bw limit given to you by ISP and you can easily compare it against graphs of traffic from ISP.

Nobody is using 10 based bytes per second.
