[docs] 3.2.2 epub docs broken

[Allan Bonadio]

the epub versions of the 3.2.2 docs are really zip files.  As  
downloaded from this dir:
http://docs.python.org/py3k/download.html

iTunes wouldn't accept them for my iPad.  And, after de-bunzip2 or  
unzip, you get a dir with Python.epub in it.  But that file seems to  
be a zip archive, with HTML files inside.  The filename list is very  
similar to the html version of the docs (which I also downloaded,  
which works well for my laptop).

(now maybe epub is really a zip file with html, not sure, but unzip  
worked on both.)

Thanks for all the work, I like the docs!
