description:
change the parsing of chown user[:gid] to the following:

1. if there is a colon present, use that as a separator for user:group

2. if there is no colon, attempt to convert the arg into a username,
   searching backwards in the string for a '.' for us.er.group

3. if the arg doesn't match a username and has a '.' in it, split it
   up and try user.group
