Fix: DiscountLimit was not scaled to 100 in MenuCategory detail. So it is now chaled in the json and scaled back in the frontend for the list as that was not supposed to be scaled.
Feature: Modifier is now done
Fix: In product save, it was checking menu_category second time again instead of sale_category
They are also linked to products / menu categroies as to which products they can be used on
The linking to menu categories is done in the frontend, database is linked directly to products
Treeview for menu categories yet to be done in modifier category detail form
