Feature Request: Print Scan Start Time

[Sajid Nawaz Khan]

After running Munin on a large hash list, found myself timing the process. This is what I did, but not sure whether it is worthy of a pull request:

munin.php, on line 26
adjust to import datetime

Immediately after Line 1211, add

scantime = datetime.datetime.now().strftime("%A %d %B %Y at %H:%M")
print("[i] Starting scan on", scantime)

Result:
