When the module was called solr we could call SearchUpdater::bind_manipulation_capture in _config.php, because
solr/_config.php was included after mysite/_config.php. This isnt true when the module is called fulltextsearch
Instead we hook into the new RequestProcessor in 3.0 to make the manipulation capture. We also make
bind_manipulation_capture re-callable, so you can call it any time you need to make sure.
