Get Hooks via ObjectManager

[sventendo]

It would be nice to have Dependency Injection for the hook objects called in \Cobweb\Linkhandler\TypolinkHandler::generateLink

        // Call registered hooks
        if (is_array($GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['linkhandler']['generateLink'])) {
            foreach ($GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['linkhandler']['generateLink'] as $className) {
                $linkParameterProcessor = GeneralUtility::makeInstance($className);
                if ($linkParameterProcessor instanceof ProcessLinkParametersInterface) {
                    $linkParameterProcessor->process($this);
                }
            }
        }

So maybe we could use the ObjectManager to get the hook objects?

I'd be glad to make a pull request.
