[feat]: Link target

[tommerkestijn]

A clear and concise description of what the feature is

It is currently not possible to add links with a different target. Also validation on the url is to strict, you can not add a path but need to add always full urls.

Why should this feature be included?

Links are a very important future and often you need to add links what are able to open in a new window.

Please provide an example for how this would work

Add a dropdown to the link popup with target option.

It is also not possible at this moment to use a: mailto:, or tel: prefix in the link.
