zipfs should support password protected zip files

[GoogleCodeExporter]

Either support the password as an optional argument to the constructor 
(preferred) or as a setter.  Looks like zipfile only supports reading encrypted 
files, not writing them, so you will probably inherit that constraint.  Still, 
reading encrypted zip files is useful.

I meant for this to be an enhancement request.  It is not a defect.  Sorry.
