Add prefix ufm filter

[erikjanwestendorp]

We often use something like this in our block list and block grid editors:

{componenttype} – {title}

For example:

Text – Component Title

Since the introduction of UFM, we’ve been using our own filter for this, namely a prefix filter. I thought this might be something that could be added by default, hence this PR.

See below how it works:

Block List with 1 block (text)

Hi @erikjanwestendorp

Thanks for your PR to add a default prefix filter for UFM block list and block grid editors.

One of the Core Collaborators team will review this as soon as possible; it seems like one that we want someone at Umbraco HQ to review, so I'll contact them about it. 👍

Best wishes

Emma
