Bug 9154 - On item edit page, highlight row of item being edited

This patch changes the item edit page to add a highlighting
background color to the row in the table of all items corresponding
to the item being edited. Changes to JavaScript have been made
to allow row color changes on hover.

Other minor edits: Capitalization corrections.

String changes, changes to JavaScript.
All tests pass.

Test plan:
1) 'Edit items' on a record with some items.
2) Check edited item is highlighted correctly in table above.
3) Add, edit, delete an item, should all work the same as before.
