Feature - Add index url_hash for performance

since verion 6.2.0

An index is added to the database table tx_brofix_broken_links for the fields link_type, url_hash and check_status. A new field url_hash is introduced which generates a hash for the URL.

This results may result in significant performance improvements when opening records with RTE fields and many links in the backend. When the RTE is opened, pre-processing is performed in order to mark the broken links as broken. For this, a db query is performed for each link.
