Display Available to Sell (Free Stock) on product page and grid

The "Inventory" figure shown within Storefeeder was always the number of items you had available to sell (stock in warehouse minus unshipped orders) , but since the advent of Quarantined locations this has got confusing as the figure shows the total units in stock, INCLUDING the items which are quarantined.

You've already added a feature to be able to export the available stock on the product exports, but it would be useful to see this figure within Storefeeder as well, both on the product page, and on the products grid.

This becomes even more relevant when looking at kit products which are made up of components where some stock is in quarantine, as it appears that we have stock available, when in fact we don't as some component parts are only available from quarantine stock.

Hope this makes sense!
