- overhauled search system
- updated structure for search backend plugins - better result caching using ACM - search results no longer session restricted => link to them by copying the URL :) - in-topic search - indexing posts now uses search backend plugins - develop/search_fill.php working again - fulltext_mysql not working yet - tiny bugfixes to ACM git-svn-id: file:///svn/phpbb/trunk@5441 89ea8834-ac86-4346-8a33-228a782c2dd0
