1.22: Records created by Crypt::PWSafe3 (eg. the ones fetched
with getrecords) are now associated with the parent
object, so that you can modify them directly and call
$vault->save afterwards without using $vault->modifyrecord.
Erase passwd from memory using zeros instead of
random bytes. fixes github#9.
Fixed rt.cpan.org#112975: Crypt::ECB (which we use) have been
reworked and among other issues it fixed handline of padding.
PWSafe3.pm did not specify a padding scheme (because it doesn't
use it) and therefore Crypt::ECB enforced a default scheme
which lead to an invalid key size. Now we specify explicitly
padding:none, as suggested by Christoph Appel.
