Removed all instances of physics.setDrawMode for easier debugging
Fixed the bug causing the player to clip through objects

It turns out Corona likes to set inactive physics objects in a sleep state. All of our problems were coming from Corona applying the sleep state to our main character. You're supposed to be able to prevent an object from going into the sleep state with the boolean myBody.isSleepingAllowed. However IT DOESN'T WORK!!!

I currently prevent the physics from going to sleep on the main character by applying a 0 impulse on every frame.
