Deprecation: #78679 - Crawler inclusion via require_once in Indexed Search 

See forge#78679

Description 

The system extension "Indexed Search" has support for EXT:crawler, by using the crawler library to index a page.

This functionality is done under the hood via the Indexer class, which does a manual PHP call on "require_once" - code which is not necessary anymore, since the TYPO3 Core class loader is in place. The public PHP method TYPO3CMSIndexedSearchIndexer->includeCrawlerClass() is therefore marked as deprecated.

Impact 

Calling the method TYPO3CMSIndexedSearchIndexer->includeCrawlerClass() will trigger a deprecation log entry.

Affected Installations 

Any TYPO3 installation with a custom indexer written in PHP, and Indexed Search and Crawler installed, and the custom indexer using the method call above.

Migration 

Remove the function call, as TYPO3 includes the PHP class automatically.
