Bug 11325: Focus not on "Add Item" in Lists

When viewing a list, the focus/cursor is no longer on the "add items" field below the list.

This patch moves the "Add Item" form at left part of page so that it is always shown (usefull when there are a lot of items). And adds focus to barcode input so you can enter several items with a barcode scanner.

Test instructions:
1. Create a list
2. Make sure you have an object with an assigned barcode
3. Go to the list
=> The barcode entry interface should be at left and has the focus
4. Enter the barcode and press enter (or use a scanner)
=> The item is added to the list
