Create logic for Orange enemy

[JoseVarelaP]

I didn't have time to implement the logic I've wanted for the Orange enemy before submitting the final version for AI class.

After my interview, I'll go ahead and implement its behavior, listed below:

The orange enemy is capable of jumping off-screen, and surprising the player in a different spot in the map. Its landing position could be indicated with a symbol moments before, but it could potentially ruin the surprise. However, not having it at all can lead to very mean or unforgiving moments.
