Your Name db2e7d1391 m25400 can now recover both a owner-password and user-password (when set) based on a pdf's o-value ...

- added option to add the user-password to the pdf hash as an extra colum
- added pdf test files, both with and without a owner- and user-password

The main todo is to add a recovered user-password to back the hash that's written to the potfile.
Currently I'm printing a recovered password as "(user password=...) after the recovered owner-password.
Similair as the VC PIM is printed. However, this isn't most elegant.

A secondary todo is to verify a recovered user-password based on the u-value,
this could possibly simplify the check whether the recoverd password is a user-password or owner-password.
