#332 Add datetime completed to report summary

[threadsafe]

Just a tiny usability nit - could you add add a scan completed datetime stamp to each scan report summary? I occasionally check the scan reports and I'd like be be able to quickly determine when the last scan was completed. Currently, I need to scroll upwards in the log viewer to figure out when the scan started. Something like this...

----------- SCAN SUMMARY -----------
Known viruses: 807018
Engine version: 0.96.1
Scanned directories: 28667
Scanned files: 217332
Infected files: 0
Data scanned: 51048.59 MB
Data read: 135101.92 MB (ratio 0.38:1)
Time: 10854.537 sec (180 m 54 s)
Scan Completed: July 25, 2010 (locale specific datetime format)

Thanks for the good work. Your windows version of clamav is highly regarded.

ClamWin already does this; I expect that means the original ClamAV does too, and so this ticket should be closed.
