        - fixed build that I broke with the license change (some includes of WebException were still around)

        * WebKit.pbproj/project.pbxproj: Removed references to WebException.h/m.
        * WebView.subproj/WebDataSource.m: Removed include of WebException.h.
        * WebView.subproj/WebHTMLView.m: Ditto.
        * WebView.subproj/WebView.m: Ditto.

        - fixed build under gcc 4.0 (some code moved here from Foundation had warnings)

        * Misc.subproj/WebNSDataExtras.m:
        (-[NSString _web_capitalizeRFC822HeaderFieldName]): Use char instead of UInt8.
        (-[NSData _webkit_guessedMIMEType]):  Use char instead of UInt8, and take out now-
        unneeded type casts.
