Changing this to "ready for review" and kindly asking for the same

[DL6ER]

This branch continues to work with the current development-v6 web branch. However, if you specifically want to review the core of this PR (being able to add multiple at once), you'll need the web interface branch new/antigravity tweak/domain_array which contains the necessary changes for this PR (sending multiple domains as an array of strings).

What's the reason to accept string and [string] and not just [string] for the relevant value? It could simply be an array of 1.

[DL6ER]

Following the REST principles, you should add/manipulate one entry per call so sending a string feels natural here. We simply extend this natural feeling by also allowing arrays. You are right, an array of size 1 is exactly identical to a naked string, however, to my understanding, rejecting plain strings and demanding them to be encapsulated in an otherwise empty array shell feels odd to me.
