Unprotect change tracking only by password verification
instead of 1) unprotecting without the password or 2) rejecting
the correct password.
I.e. now 1) clicking on Record changes icon of Track Changes
toolbar or Edit->Track Changes->Record asks for a password, and
2) Unprotect Record changes on Security page of
File->Properties... accepts the correct password with disabling
record changes.
Show also "Invalid password!" dialog disabling Record Changes
by its icon or menu option, like Properties... dialog window does,
if the password is invalid.
Note: Still allow to unprotect OpenDocument export of a
protected OOXML import document, because that doesn't contain
the original password info, only a dummy RedlinePassword.
(OpenDocument exports protect Track Changes with the simple
RedlineProtectionKey configuration setting, so it's not
possible to map the OOXML password info to OpenDocument without
extending this.)
