Add the option of Soy Butter to the WIC program

Allow recipients of WIC to receive soy butter in place of peanut butter. Many children are highly allergic to Peanuts and the WIC program does not accommodate them by providing Soy Butter instead of Peanut butter. Furthermore, many schools are peanut free. So low income parents even non-allergic students can't use the peanut butter to make their children lunch.
