Sam Atkins 9b53baa652 LibWebView: Track recently closed tabs and windows 
Maintain a stack of URLs and when they were closed, and allow popping
the most recent one.

These are stored directly on HistoryStore instead of its Storage object,
because they should never persist regardless of which backend we're
using. Even so, we still clear them along with other history data.
