Enable Google Analytics

[hubertus65]

We have discussed back and forth whether to allow google analytics on MA web pages. However, enabling analytics might give us useful info to improve our marketing. I suggest to make an experiment on fmi-standard.org, collect data for some time and see what we get from it. @t-sommer, I think this is quite easy?

For fmi-standard.org GA has been enabled for years. To enable it, all you have to do is create a GTAG and add it to the configuration.
