Native menu and log support

[pammacdotnet]

I've added native menus and system logging support from within apps. Everything is explained in my README.md.

I hope you'll find it useful. Thanks for your work. Greetings from Spain. Alberto.

Thanks for your work on this. I am wondering whether you would consider extending this so that we could:

• add / remove menu items in existing menus
• activate menu items such as File > New
• specify the position of new menus (instead of placing them after the Help menu) and new menu items.

I have just committed code which adds menu support. Some of the code was taken from your commit here, so thanks for your work.

Can you explain the need for a log-NSLog bridge? I just use the webview's developer tools to see the console output.

Since MacGap already contains the following I'm not seeing the purpose of the NSlog bridge in your code, sorry! Please do re-open this if I've missed something that the following doesn't provide.

- (void) webView:(WebView*)webView addMessageToConsole:(NSDictionary*)message
{
    if (![message isKindOfClass:[NSDictionary class]]) { 
        return;
    }

    NSLog(@"JavaScript console: %@:%@: %@", 
          [[message objectForKey:@"sourceURL"] lastPathComponent],  // could be nil
          [message objectForKey:@"lineNumber"],
          [message objectForKey:@"message"]);
}
