Title: [Browser] Automatically reload tabs killed in the background, closes #3781

* If a fatal mozbrowsererror event is received while the browser app is in the background, app is marked as "killed" rather than "crashed"
* When the browser is brought back into the foreground, the current tab reloads
* Any other killed tabs reload when you select them
