Absolute paths for link checker and baseURL (#1369)

* Absolute paths for link checker and baseURL

* Fix json syntax

* Modify file to trigger link check

* Trigger another check

* Run over all files

* Revert to changed file check only

The full check takes way too long and can result in false positives as well
(full checks are what made the old link checker unusable in the end).
