Added a debug console

Open it by pressing backtick, close it by hitting escape. Pressing backtick does not open it in release builds.

Current shortcomings: opening it for the first time also types a backtick for some reason, but not on subsequent times. Also, it doesn't create a coroutine, so any script function that yields is going to fail.

This also added a "is gameplay paused" flag to Game, which will be useful for adding a pause menu.
