Add :preload option to find
Reported by Will Bryant | January 11th, 2010 @ 10:40 AM
This patch adds support for a :preload option, which functions much like the "new" :include path - but it will always use that rather than falling back to the old join-based :include path if the query options reference other tables.
Thus, it makes it possible to preload polymorphic associations even if you have some table conditions, other joins, or a multi-table :select option, and ensures you don't get O(n^m|m = number of loaded tables) resultsets in these conditions. It supports using both :include and :preload in one find, which is quite useful if you want to include to restrict the resultset but preload to efficiently load associations.
This should enable us to pass the bitter, cold evenings until 3.0 brings new association love.

It is still an issue on 2-3-stable. The patch does contain tests. It still applies cleanly to 2-3-stable.
(master doesn't need this though.)

Thank you for responding Will. Unfortunately this patch changes the user facing API. Since 2.3 is only being supported for bug fixes this patch cannot be applied any longer.
