In product detail page :
- show slider with product associated accessories if any, above the best selling products slider
- show product's family best selling instead of the accessories, if any
- show no slider if no accessories nor family best selling present
Cache slider templates for :
- associated accessories for each product for every language, if any
- family best selling for each family of the product for every language, if any
Fixes in javascript :
- missing globals variables in module expresscart would the express cart fail when out of stock
- change the express cart displaying when clicking on the cart icon in any footer sliders.
Css :
duplicate all css styles 'best-sellers_block_product' in 'privatesales_similarproduct' so that the latter slider can be adapted if required.
