Title: Bug 877579 - Items in the awesome list flicker as the user types a URL

When the user types a URL in the browser, the awesome list suggests similarly spelled URLs/items. But the list is recreated for every keystroke, causing visual glitches (flickering and unnecessary processing and DOM reflows.

This patch caches recently used items in the awesome bar to avoid reconstructing it every time with the same markup.
