Improvement: Now you can check stock on hand quantities from invoices and other transactions

We have released yesterday a nice improvement for inventory users: from any transaction (invoices, bills and inventory adjustments) you can check the item's:
- Stock on and quantity
- Quantity on Order with Supplier
- Average cost of the item

This way you can make decisions without living the page. 

Additionally, if needed, you can now go to any item directly from transactional pages by clicking on the edit item link.
