Remove GIT_ID constant and git id from file header comment.

These were unecessary and only cluttered the files.
Minor corrections.
Add static Vector2 operations.

The Vector2 class does not have operations that do not modify the vector. It also does not support multiplying a Vector2 with another Vector2.
Can now set the character's position through a Vector2.

This allows vector math to be used instead of modifying the vector components individually. Vector component manipulation can still be done, if necessary.
Update Block class to be a true base class.

The Block class did not provide any functionality; now it does. The WoodBlock class was modified to use this functionality, which included switching to using a Sprite.
Modify Player and BasicEnemy to use vector math.

The animation was messing up because not all key frames were being flipped. Also, got rid of the position vector, as it was redundant.
