Parameter "account" not need in most cases

[ftputiluser]

AFAIK parameter "account" is not needed in most cases.

I guess the docs would be better for newbees, if the first usage example of FTPHost does not use it:

http://ftputil.sschwarzer.net/trac/wiki/Documentation#ftphost-objects

And I would explain session_factory=ftplib.FTP later, not on the first usage example.

I agree that account and session_factory aren't needed for the "basics" as the subsection is titled. :-)

By the way, it's rare that someone notices such "usability' issues in the documentaton, so I'm especially thankful for feedback like this. Are there other things that could be improved?

Improved the documentation in [52b8ea2582cc].
