Instead of hardcoding and tight coupling of relation resolving, we now
provide a dataprocessor instead.
Therefore you need to configure resolving for each indexed type.
This resolves#149 and #147.
Before this change, sys_language_uid was indexed as an empty string, due
to internal used TYPO3 API.
We now skip the configure field which defines language uid. This way you
can build filter based on current language.
Resolves#148
* Add typoscript option which TYPO3 tables should be processed and which
should not be processed.
* Respect new optiion in hook.
* Also add necessary tests.
* Remove old no longer needed tests for hook.
* 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.
