!!![FEATURE] Better handling of link target results

This is a breaking change! It is advised to look at the
Changelog in the documentation for more information.

The checkLinks functions in all LinktypeInterface classes now
results a LinkTargetResponse object. In this, a status is
stored for the link checking, which makes it easier to handling
other link target status apart from broken.

This effectively makes the following possible:

- show all links in the broken link list, not just the broken links
- better handling of link targets, which can't be checked. This includes
  for example URLs with 401 or 403 HTTP status codes, where it is not
  possible to check the URLs. Previously, these URLs were considered
  broken while in fact we do not know if they are broken or not and
  we have no was to check them. This also includes URLs protected
  by cloudflare. They are now stored not as broken but as "can't be
  checked"
- it is possible to filter in the link list by this new status
