Adding new discount types

[divs1210]

Hey! How can I add more types of discounts to my app without incurring downtime? (because i'll have to add code to CONFIG_OPTIONS in plata.discount.models)

You should probably do it this way (appending to Discount.CONFIG_OPTIONS):

The calls to explicit_products and only_categories should be placed in a models file; maybe AppConfig also works.
