Passing ftp connection params in extended format

Fix for #19 and related welaika/wordmove#320

Generally approve, but a question - not born from your code -: why are we URL-encoding the password instead of using Shellwords.escape? Isn't that string constructed to be a system call?

[mukkoo]

Nice question. I think that CGI.escape is an old (unquoted) implementation.
Since version 1.0.0.pre has been introduced Shellwords.
In this specific case can be easier to leave CGI.escape because command in into a quoted context

lftp -c 'set ftp:list-options -a; set cmd:fail-exit true; open --user user --password password --parallel=5 --reverse --dereference --exclude-glob .git --exclude-glob *.sql --exclude-glob bin/'

We should plan make a Wordmove's release with the updated dependency
