fixes#16: support the CiviCRM 5.67 log format

[mlutfy]

Tested on 5.67 (well, I had backported the date format patch to our environment).

It also bumps the version and the minimum-requirement, so that people on < 5.67 do not upgrade the extension.

Thank you, but you know you're rewarding my laziness?

Sometimes lazyness is a good investment ;)
