ls, stat: Show more info in long format on Windows

[tertsdiepraam]

Fixes a bit of #3544

I kept the format identical to the format and Unix and approximated the permissions for Windows. Here's an example of the output:

total 0
drwxrwxrwx 1 somebody somegroup 0 Oct  9 00:36 directory
-rwxrwxrwx 1 somebody somegroup 0 Oct  9 00:30 link
-rwxrwxrwx 1 somebody somegroup 0 Oct  9 00:30 read-and-write
-r-xr-xr-x 1 somebody somegroup 0 Oct  9 00:30 readonly

Unfortunately, I can't get the link to work under Wine. I'm not sure if it's an issue with Wine or with the util (it'd be great if someone on Windows could test this. @AndreasBrostrom, maybe?)
