Ok.  I looked into it and fixed it in the ooo-build-3-1-1 branch as well
as on master.

The problem was that documents created by the older versions of Go-OO as
well as the upstream OOo did not always specify password hash.  So I was
not applying any hash to the password text before verifying it, when in
fact I was supposed to use SHA1 hash when no hash algorithm was
specified.

Anyway, feel free to grab the latest from the ooo-build-3-1-1 branch and
give it a try.
