Modifying the autocache behaviour to automatically cache all database queries on the site.
This will automatically invalidate all entries for a model if an item is modified or deleted. Pressing "Refresh" will also invalidate the cache.

This modification means that you don't need to put "autocache" => true into your queries, all queries will be cached by default.
To prevent caching, you can put "autocache' => false if you like.
