BidiMode improvments patch

[Zaher]

I know i touch a sensitive code but we can discuss about it.

Added TVisualCompont it is between TLCLComponent and and TControl, it has a properties and methods that have visual effect but still it unvisible at form. i will use it for BidiMode and ParentBidimode
TMenu, TPopupMenu, TScreen, TTrayIcon and TPopupNotifier and any component need bidimode , TTheme and TToolbar...

Now it can detect if the Component was inherited from TVisualComponent to make loop when BidiMode changed in the form/control.

Remove duplicating of implement the same code in both TControl and TMenu and every TComponent need the BidiMode.

I kept UseRightToLeftScrollBar in TControl

Added BidiMode to TApplication.

TApplicationProperties must *not* inherite it from TVisualComponent it is like TApplication have no ParentBidiMode

I used the forum for my patch, because i like to edit my posts, but i can use Mail-List if you wish.

I would leave class hierarchi as is. No idea what other developers think.

[Zaher]

I can merge of BidiMode the into TLCLComponent.

[Vincent Snijders]

For discussion with all developers, the mailing list is a better platform.

[Zaher]

Ok, I will repost the patch and my post in mail the list.
