- improvements to search indexing performance, espacially tidy() by adding a word_count column, the database update from b5 to next version will take quite a while on bigger databases, I also lowered the default common word threshold from 20 to 5 percent, big boards might want to use 3 or 2 percent, 20 was way too high

- added some keys to ACL tables, great improvement of auth query performance
- we will only add new language strings to install.php language file and won't modify any, if a language file is updated before phpBB is updated, the updater will not overwrite the user's language with english if install.php was modified
