Link field: support for link text and target

The new links field in v4 is good, yet I prefer the approach of https://github.com/OblikStudio/kirby-link-field – allowing custom link texts and also setting the target comes really handy.

I agree. Additionally, it would be useful to store information about the link type in the field (either as yaml or json), so as to easily get the title from a page or meta data from file for these link types conditionally.
