[dspam-users] dspam.cgi patch (history + getprefs)

Hello,
    I made a small patch to the web interface (dspam 4.6.2). Changes
in this patch:

    * change in DisplayHistory so you can change the date format from a
      parameter in the configure.pl file. If the variable is undefined,
      it behaves as it did before. Otherwise use it to choose your date
      format in strftime style.
      $CONFIG{'DATE_FORMAT'} = "%y/%m/%d@%H:%M"; # Date format in
      strftime style
    * change in DisplayHistory to read the entire log file to select
      which lines to display and avoid wrong displays because of
      incomplete information availability
    * workaround in GetPrefs to read the default parameters before
      reading the user specific parameters (this should be a temporary
      workaround until dspam_admin aggr prefs is fixed)
