Frontend: Please don't prefill new cards in Lovelace's visual card editor

[noxhirsch]

The request

Everytime I add a new card in Lovelace UI, the card is prefilled with random entities and in case of the entities-card with a useless title "My Title". This is pretty annoying, because I have to remove all this stuff first before I can use the card.
I understand that this is maybe nice for beginners which don't know how editing the UI works. So this behaviour could be connected with advanced mode - if it's off, the cards get prefilled - if it's on, the cards don't get prefilled.

The alternatives

Alternatively only the first time a user adds a new card, the card gets prefilled. But I think that's more complex, because HA would need to set another flag for each user.

You can just press the "manual" button at the bottom left if you want an empty config?

[noxhirsch]

Maybe my text wasn't very clear on that, sorry! I don't want an empty card config, but an empty visual editor instead.

We discussed this a bit in chat, think a 'clear' button would make most sense as a compromise on this.

I think that's a good compromise, because it could be useful in other cases, too 👍
