Add forward and back buttons to organize column search

[dsmmcken]

• Initial search should still select all items, and scroll into view the first item.
• Pressing left/right arrow should scroll into view the previous/next item, and select just that item. Show N of M for indicator
• Navigation should loop, pressing previous on first should go to last item and vice versa.

Note make sure padding is increased on the input when the buttons appear, so that it doesn't overlap the search text.
