        - fixed the build on Panther

        * WebView.subproj/WebFormDataStream.m: (webSetHTTPBody):
        Added a Panther-specific code path that just loads all the data into one big
        NSData object. This means that bug 3686434 won't be fixed on SUPanWheat; we'll
        still load the file into memory before sending it to the server on Panther.
