OR/OMNI

OR gates are implemented, but be warned, I may change how the gates are loaded (so it's easier to change/add gates). I want to make it so that all the gate logic is loaded from a file, instead of hard coded in. OMNI gates are coming soon. I'm not going to give any hints, but there will be more depth added to levels with this. Obviously, omnigates will be the only thing that will not be added to the file (as they are more complex).
