Fixed issues with changing AA and AF...

-AF change no longer reloads the window to apply. Doing such isn't needed anymore.
-AA change no longer reloads the window to apply, IFF RenderUseFBO is true.
-AA change, IFF RenderUseFBO is false, reloads window. Texture issues under this scenario should be resolved.
-LLComboBox now updates control_name it's linked to, automatically.
-New LLComboBox Behavor when paired with new AA/AF application changes renders LLFloaterHardwareSettings::apply() pointless, EXCEPT for when changing AA while FBOs are off.
