separate number of bytes into 3-digit groups

[mwinterrowd]

For each file, the transfer queue window shows the
number of bytes that have already been transferred,
like this:
37890695 bytes (30.7 KB/s)

There should be an option to separate this number into
groups of three digits, like this:
37.890.695 bytes (30.7 KB/s)

Taken from now closed:
[ 1323330 ] Commas in Bytes (File Size)

"When displaying file sizes (both local and remote) in bytes, could you add commas when then sizes are formatted? E.g., show "1,234,567" rather than "1234567"? In Windows, I believe you can ask the system for the symbol, and display "1.234.567" or "1 234 567" in countries where appropriate."

and...

"Or change unit (bytes, KB, MB, GB)..."
