	Re-fix of 3113393 - Clients side redirects shouldn't always add item to back/forward list

	Fix 3116980 - REGRESSION: Back button goes back twice

	Fix 3099631 - assertion failure at http://www.calendarlive.com/ when pop-up blocking is off

	The earlier fix for the first bug was to consider any redirect happening within one

	second as a continuation of the previous load.  To fix the regressions I re-cast that

	fix using a similar, pre-existing mechanism.

	Fixed: 3115073 - REGRESSION: plants.com is crashing in WebIconDB with bad retain count

	The plants.com favicon was marked to be removed from disk and thus it had no retain count. The problem was that it was still on disk and _hasIconForIconURL would return YES. If hasIconForIconURL returns YES, its is ok to call  _setIconURL:forSiteURL:. Since there was no retain count, the assert in _setIconURL:forSiteURL: would be hit.

	We now consider icons without retain counts to not exist even if they're on disk.
