[#34] Platform edges shouldn't stop forward progress

* Fixed. Users can now hold down right/left and will clear over the edge of the platform if they are going in an upward direction.
* This also fixes the problem where if a user hit an edge, they would fall to the bottom, but still appear to be running. 
* Essentially, as long a player holds <- or ->, the game will continue to treat them a 'running' until the key is released.
