Test Mode (Zoi Mode) for Build Studio

Building is much easier overall in Build Studio where you don't have to contend with other buildings getting in the way. However, as it's not in the main game world, there's no way to test to make sure pathing for Zois works properly or to confirm that things are working right. 

A test mode where we can activate a zoi to move around in the build would be an excellent way to avoid issues, prior to uploading to Canvas, or having to switch back and forth between the game world and studio mode.

For example, I have a property build where the platforms decided to break and my Zoi walk completely through them. If there was a test mode, I'd be able to see the issue and hopefully fix it.
