Add .Site.IsServer to determine if the site was built in server mode

[mydoghasworms]

As per the following Discourse discussion:

https://discourse.gohugo.io/t/disable-portions-of-content-while-developing/10860

It would be helpful to put a condition into a template that can determine whether the page is being built/server by hugo server (and not necessarily with the -D flag, for which there is already a variable).

This would be helpful for the case where you want to test the site in its final form (no drafts) but want to switch off, e.g. analytics or ads.

But isn't this already possible by simply checking if .Site.BaseURL is "localhost"? I do that all the time.

Not if you run your server with something other than "localhost". I do that all the time. You could, of course, adjust that logic to also check for that hostname, but that would hardly be very portable.
