Change variables from console window

[PxlBuzzard]

I imagine syntax like myObject.Position.x = 20. The console could be done in-game via Awesomium if that's what we pick for the UI, or it could be a command-line window seperate from the game.

Prereq: threading

[ColdenCullen]

If we use Awesomium or similar we don't need threading, the issue is that readln() is blocking, so waiting for info would stop the rest of the engine from running.
