Keypresses are still recorded when window not in focus

[ChaseCarlson]

The editor still listens for keypresses even when I'm on another window. For example, as I'm typing this in my browser, the game zooms in and out every time I type the "I" and "O" keys.

I would go into the code and fix this as I'm working on a similar project atm but there's a bunch of include errors I don't want to bother playing around with.

I should really address this, perhaps seperately from DataModelV3
