Out of stock product is not showing the error

[shabnam611]

When a product is out of stock and when the product is added from viewPOS section, it simply doesn't do anything.

An alert that says the product is out of stock would be a great solution to this issue.

It would also be nice if out-of-stock products are showing grayed out or with a cross overlayed in the article overview, so that one is not even tempted to add an out of stock product. Phantastic POS, thanks!
