- removed search settings from load page

- no need to retrieve mysql information on every page => removed (fulltext_mysql)
- added init() method to search plugins which is called when the search backend is changed
- optional create/delete index functions for methods which don't need to loop through all posts (like fulltext_mysql)
- index statistic functions for search plugins, displayed on acp search index page
- only remove words above 60% (fulltext_phpbb)
- added acp method to search plugins so they can display config options specific to a certain search backend
- renamed fulltext_phpbb specific options to make clear that they are a part of the plugin
- reordered lang entries for the load settings section

added acp_search.php:
- settings: general options / search backend / backend specific options
- index: statistics / delete index / create index (progress popup while processing)
