[feature-request] Show a promo/sale/discount banner in the pricing page

[bfintal]

Not necessarily an SDK feature, but I would like to suggest a new area in the Freemius dashboard for adding a text banner within the pricing and checkout page.

This can area can be used to display promos, sales, discounts or any information related to new purchases.

My temporary solution to this is to add some custom CSS:

#wrap_section:before {
    content: "Some text";
    display: block;
    ...
}
