Compatibility to TYPO3 8.7

[MarkusBausK]

Hi,

do you plan to maintain your extension to support TYPO3 8?

I installed it and it is possible to add categories as filters. They are perfectly shown in frontend but all results are 0. Maybe I did something wrong (but I don't know what this could be) or it depends to changes in versions of TYPO3 or ke_search.

If you can live with manually creating a filter option for every system category, then ke_search supports filtering by categories already, sort of:
