In the recursive test we expect it to be able to download all 3 files

And the downloaded file structure is as follows:
{code}
E:\workspace\camel\components\camel-ftp\target\ftptest>dir /s/b
E:\workspace\camel\components\camel-ftp\target\ftptest\foo.txt
E:\workspace\camel\components\camel-ftp\target\ftptest\sub-a
E:\workspace\camel\components\camel-ftp\target\ftptest\sub-b
E:\workspace\camel\components\camel-ftp\target\ftptest\sub-a\a.txt
E:\workspace\camel\components\camel-ftp\target\ftptest\sub-b\b.txt
{code}

In this simple test it download the 3 files from the FileZilla server and put the file in
the expected directory on the consumer side.
Notice that we don't have the leading one/two folders in the downloaded structure which is
expected.

>             Project: Apache Camel
>          Issue Type: Improvement
>          Components: camel-ftp
>    Affects Versions: 2.5.0

>            Assignee: Claus Ibsen
>         Attachments: camel-ftp.patch

> In Camel 2.5, the logic for changing directory for ftp/ftps/sftp has changed in order
to fix the problems discussed in the following thread:
>   http://camel.465427.n5.nabble.com/How-to-change-directory-while-using-sftp-component-td2806817.html#a2807611
> In Camel 2.5 changing of the remote directory is now done in a stepwise manner. This
is a strategy not fit for production since it assumes that the logged in ftp/ftps/sftp user
has access to all intermediate directories all the way down to its home directory. This is
rarely the case.
> Also, when testing ftp/sftp on Serv-U, a Windows based ftp/ftps/sftp server, it turns
out that it reports the current directory in a "Windows way", e g /C:/temp/servu/user/sample/file2sftp.
The topmost folder is not "/" but "/C:". This also breaks the new stepwise way of changing
directory since it always tries to change to "/" if an absolute path is used.
> I propose to introduce a configuration property to enable/disable stepwise changing of
directories where disabling it should be the default. I will upload a patch shortly.
