Block grouping in Blocklist

[madsoulswe]

Add a field to enable grouping of blocklists, similar to Propertyeditors.

Here is a simple example

Unlike groups in property editors, we may also need to consider localization here. For example using dictionary items and the syntax "#Header". Honestly I haven't checked if the Label property supports this feature like Label and Description on content types.

I don't know if this is a Umbraco Forms only feature, but "magic strings" would be a plausible solution? I would like to see it slowly integrated across all of Umbraco if it could be.

I feel the need to state that the current implementation of "magic strings" seems funky to me from a FED perspective. I'd like to see improvements here too.

Our entire UI library is composed of blocks, and as such, this list can grow unwieldy. Any form of added categorization, sorting, and filtering would be a welcome addition and improve the editor's experience.
