* Allow configuration through TypoScript to exclude records for indexing
based on their root line position. Page uids can be configured for
exclusion and all records beneath will be excluded while indexing.
* TCAIndexer is now able to resolve relations of any kind by using TYPO3
Core API.
* Indexed will be a single string or an array, depending of how many
relations were resolved.
* The same value will be indexed as shown by TCA in backend while
editing or displaying.
