Bug 313715: "Open in New Tab" from Bookmark Manager doesn't respect background pref

Stop caching the result of shouldLoadTabInBackground(), there's no point since we need to look at the state of the shift key every time, and we didn't update it in all code paths to begin with.
Pass in |event| from more places in history and bookmarks so we'll actually look at te shift key.
Replace use of "tab_background" with looking at shouldLoadTabInBackground().
