Replace ugly abuse of log pages to store cached results of query pages with a table that stores up to 1000 rows for each 'expensive' special page. This can be paged through, reducing the annoyingness of 50 result limits on the old system. Rebuilding the cache can be forced by adding "recache=1" URL parameter, but this will need to be refined with some sort of controls to prevent abuse. Added the user realname update to the installer's updater list, also. 2004-05-09 01:30:34 +00:00			`-- Used for caching expensive grouped queries`
