[#1040943] Exit editor mode without relaunching the game

[Xd-pro]

Currently you can't and it makes going in and out of editor mode for testing annoying

[novam77]

causes irritation every time you try to do it again. it would be nice to find a loophole in this

We've moved up the priority of a feature we're referring to internally as "Edit/Test" -- stay tuned, but it should ease a bit of the pain in this very clunky workflow!!
