Preserve Timestamps in History and 'Last Access'

[mrkdev]

In the current version (0.4.1) timestamps in the password history get messed up (changed to current date on all versions).

The same is true for the timestamp 'last access' - all passwords timestamps change to the current date independant if they where really accessed in the current session or not.

(For both: the passwords oringinate from KeePass - I did not check if this does not happen if you created them in MacPass only. I use the same database file with MacPass and KeePass on a regular basis.)
