Allows FTP servers on Linux to delete files starting with a dot.

[UltraNamahage]

Fix #99.

Linux-based FTP servers often consider files starting with a dot to be hidden files.
The "-al" option allows you to retrieve them.
However, it is not included in RFC959.

This option should not work with ftp-srv on win, for example.

What do you mean by should not work? What will happen on a windows server with your code?

@simonh1000 Thanks for looking.
It outputs a lot of this stuff.

but that means your code will break some people's setups?

There should be no major problems.
In the worst case, a slowdown in processing speed can be expected.
