          XMLHttpRequest: PUT, DELETE, HEAD and all other methods but POST actually do a GET.

        HEAD is currently unimplemented because of what seems to be a bug in NSURLConnection,
        and does a GET instead.

WebCore:
        * kwq/KWQKJobClasses.h: Add a method parameter to TransferJob.
        * kwq/KWQKJobClasses.mm:
        (WebCore::TransferJobPrivate::TransferJobPrivate):
        (WebCore::TransferJob::TransferJob):
        (WebCore::TransferJob::method):
        * bridge/mac/WebCoreFrameBridge.h: URL loading functions now take a method parameter.
        * dom/xml_tokenizer.cpp:
        (WebCore::openFunc):
        * khtml/xsl/xslt_processorimpl.cpp:
        (DOM::docLoaderFunc):
        * kwq/KWQLoader.mm:
        (KWQServeRequest):
        (KWQServeSynchronousRequest):
        * loader/loader.cpp:
        (WebCore::Loader::servePendingRequests):
        * page/Frame.cpp:
        (WebCore::Frame::didOpenURL):
        * xml/xmlhttprequest.cpp:
        (WebCore::XMLHttpRequest::send): Honor the method passed in open().
        * khtml/ecma/JSXMLHttpRequest.cpp:
        (KJS::JSXMLHttpRequestProtoFunc::callAsFunction): Don't serialize null as "null".

WebKit:
        All WebKit changes are to use the method parameter passed from WebCore.

        * WebCoreSupport/WebFrameBridge.m:
        (-[WebFrameBridge startLoadingResource:withMethod:URL:customHeaders:]):
        (-[WebFrameBridge startLoadingResource:withMethod:URL:customHeaders:postData:]):
        (-[WebFrameBridge syncLoadResourceWithMethod:URL:customHeaders:postData:finalURL:responseHeaders:statusCode:]):
        * WebCoreSupport/WebSubresourceLoader.h:
        * WebCoreSupport/WebSubresourceLoader.m:
        (+[WebSubresourceLoader startLoadingResource:withMethod:URL:customHeaders:referrer:forDataSource:]):
        (+[WebSubresourceLoader startLoadingResource:withMethod:URL:customHeaders:postData:referrer:forDataSource:]):
