Discovered while working on <rdar://problem/5070334> that many WebView calls will crash if called
after -[WebView close] has executed because _private->page is deferenced after it's been set to 0.
It might be silly/wrong to call these methods after -close, but obviously it shouldn't crash. Made
each use of _private->page robust against nil-dereferencing.
