Subject: [PATCH] Store only the the .Game property when importing a game
 engine

Previously, we were referencing engine.Game separately from
engine.router, etc. But now that engine.Game is the only property
that's part of the interface, let's dereference that immediately at
the time of require() so that later on we can just use "engine" in
place of "engine.Game".
