Message:

i Added a debug menu to turn back/forward cache on and off.

Off by default. Use with discretion. Still leaks like
a sieve. Useful to provide a sense of potential speed up.

Changes fro back/forward cache.

• History.subproj/WebHistoryItem.h:
• History.subproj/WebHistoryItem.m: (+[WebHistoryItem setUsePageCache:]): (+[WebHistoryItem usePageCache]):
• WebCoreSupport.subproj/WebBridge.m: (-[WebBridge saveDocumentToPageCache:]):
• WebView.subproj/WebFramePrivate.h:
• WebView.subproj/WebFramePrivate.m: (-[WebFrame _detachFromParent]): (-[WebFrame _canCachePage]): (-[WebFrame _setState:]):

Tweaked some debugging info.

• khtml/xml/dom_docimpl.cpp: (DocumentImpl::~DocumentImpl): (DocumentImpl::detach):

Added debugging info. Fixed property map save function.
