Added Backbone for Turn System, Spring Break Next Week

The past week has been spent focusing on developing a turn-based system and added a second player (represented by the raccoon character).

A backbone was added to allow for a 2-player turn-based system. Coroutines were needed in order to keep the game from freezing up; however, the coroutine system does not enforce each player going one at a time. Therefore, an arbitrary time wait has been temporarily added until a better solution can be found. Similarly, there is a temporary system that selects a random number between 1-6 for the character to move forward rather than utilizing the dice system.
