Title: Allow USERNAME to be specified on the command line.

There are some systems that have usernames of the form DOMAIN\username,
which causes an invalid escape character to be inserted. I was going to
add some escaping, but decided it would be best to just outright set the
value, since I don't want the DOMAIN portion in there anyways.
