        <rdar://problem/3655241> setTypingStyle: does not set the real typing style, and typingStyle does not return it

        * khtml/khtml_part.cpp:
        (KHTMLPart::computeAndSetTypingStyle): New helper that does the work of reducing a passed-in style
        declaration given the current selection, and then sets the minimum necessary style as the typing
        style on the part.
        (KHTMLPart::applyStyle): Call new computeAndSetTypingStyle. The guts of computeAndSetTypingStyle used
        to be here in the selection-as-caret case. But now [WebCoreBridge setTypingStyle:] needs this code
        as well.
        * khtml/khtml_part.h: Declare new computeAndSetTypingStyle() function.
        * kwq/WebCoreBridge.h: Declare new typingStyle and setTypingStyle: methods.
        * kwq/WebCoreBridge.mm:
        (-[WebCoreBridge typingStyle]): Calls through to the part to retrieve the typing style.
        (-[WebCoreBridge setTypingStyle:]): Calls through to the part to set the typing style.

        <rdar://problem/3655241> setTypingStyle: does not set the real typing style, and typingStyle does not return it

        * WebCoreSupport.subproj/WebBridge.m:
        (-[WebBridge respondToChangedContents]): No longer call through to WebKit to set the typing style. The call
        was part of the misguided use of the setTypingStyle: and typingStyle as a cache of what was stored on
        the WebCore side.
        (-[WebBridge respondToChangedSelection]): Ditto.
        * WebView.subproj/WebView.m:
        (-[WebViewPrivate dealloc]): Object no longer has typingStyle ivar.
        (-[WebView setTypingStyle:]): Call over the bridge to set typing style.
        (-[WebView typingStyle]): Call over the bridge to retrieve typing style.
        * WebView.subproj/WebViewInternal.h: Object no longer has typingStyle ivar.
