fix notice for data config
fix number formattings, added country,
added style for number alignment
added support for variation price, fixed rendering of empty table cells
fixed cart price calculation with repeaters

added 2 new methods to cart
- getProductPrice($item) will return product price from either repeater
or product page
- getProductPriceTotal($item) will return product price total for
quantity in $item->qty
- made those methods bookable also so they could be modified maybe
useful for discounts etc.
- updated checkout module for price calculation
