I fixed the crash part. Not the "gives null view" part.
	The key was to disentangle the references and lifetimes of the transfer job class,
	and the resource loader object that KWQ uses to connect it with WebKit.

        * kwq/KWQKJobClasses.h: Change the job to keep a loader reference, not a
	handle reference. The job needs to inform the loader when it's being deallocated.
        * kwq/KWQKJobClasses.mm: Use jobWillBeDeallocated instead of cancel when the
	job is deallocated.

        * kwq/KWQLoader.mm: (KWQServeRequest): Use KWQResourceLoader, now with a home in
	a separate file.

        * kwq/KWQResourceLoader.h: Added.
        * kwq/KWQResourceLoader.mm: Added.
        * WebCore.pbproj/project.pbxproj: Added KWQResourceLoader files.
