parseRFC3659ListLine Fails to parse MLSD (List) response

[laraoz]

The issue lies in the parser.go file. It seems that when you issue a List command (MLSD supported), the parseRFC3659ListLine function can't work with keys where the first letter is an UpperCase. It seems to always expect a lowercase string (from line variable), which is not always the case (at least in my server). Instead of getting things like type=cdir - which expects - , it gets Type=cdir, so it fails to match that in the switch statement and sets everything to 0 or nil.

If i can make a suggestion, format the key at assign at
https://github.com/jlaffaye/ftp/blob/master/parse.go#L43

key := strings.ToLower(field[:i])

Yup, I did that in my local, but problem remains for others
