GameObject Sprites

[lukalelovic]

Currently a GameObject is represented on the screen by a single character. This will not do for projects where the user wants bigger ascii art pieces to control (such as a car, plane, UFO, etc).

How this can be done:

1. Changing the GameObject pt char data member to an array of characters (or a string)
2. Storing each position of an array of characters (relative to the GameObject)
3. OR, plotting an array of characters around the GameObject position (could result in some weird behavior but might be the easiest solution)

GameObject sprites are implemented. Sprite animations are needed next.
