can't detectSystemType for windows

[bblemm]

Bug Report

Q	A
BC Break	no
Version	1.1.5

Summary

The response from windows-ftp-server has a human readable format.
This contains padding whitespaces.

In function normalizeWindowsObject() is a trim used for this problem,
but in detectSystemType() is the item unfiltered used and the function returns always ‘unix’.

Finally, the item can’t be normalized because there are no 9 parts for unix format.

How to reproduce

Testable with windows server or with unit test, response has prefixed white spaces in meta data.

Test

tests/FtpTests.php
if (strpos($directory, 'file4.txt') !== false) { return [ ' 2016-05-23 12:09PM 684 file4.txt', ]; }

Fix

protected function detectSystemType($item) { return preg_match('/^[0-9]{2,4}-[0-9]{2}-[0-9]{2}/', trim($item)) ? 'windows' : 'unix'; }
