Y johnny can't hide

Hey Folks -

so in the TGE world editor, the "Hide Selection" option hasn't worked for a long time,
and i'd always assumed i'd broken something,
but in trying to fix it today, i think it may never have worked since at least TGE 1.3.5.

Here's the flow:

1. Hide/Unhide selection set a dynamic script field named "hidden" in the item to true or false.
2. In InteriorInstance::renderObject(), we have:

if(gEditingMission && isHidden())
      return;

3. isHidden() just returns the value of the dynamic field.

Seems Good,
except that EditTSCtrl::renderWorld() looks like this:

void EditTSCtrl::renderWorld(const RectI & updateRect)
{
   // .. set some GL states ..

   gClientSceneGraph->renderScene();

   // ..

see the problem ?




i tried having renderWorld() render gServerSceneGraph, but it got some funky errors which i don't want to track down.

so, proposed solution:
have Hide/Unhide selection set the "hidden" dynamic field in the server object and then lookup the client version of the object and if it exists, set it there too.
