need more restriction regarding the cart quantity

[GoogleCodeExporter]

first issue:

1. on cart page. have selected few items on the cart.
2. click on update quantity. 
3. if leaving the field emptied, and save
4. a blank page will appear. 
5. the cart will become not available. 
6. manually have to set that id on shopping_item to some value to fix it.

second issue.
1. on cart page.
2. click on update quantity. 
3. put a value more than it has in stock. i.e. 10000000
4. should display  "quantity is more than available", but the quantity is set 
into the system.

also, why can't we edit another row on the update quantity. instead, we need to 
save and click another row to edit another item.

now.
when a user enter more than it is available. it will display a hint to ask a 
user to check if (s)he has order more than available.
