Added my sdl timer class so camera movement is time based not fps based
Removed xyz enum because it's defined in vec4 now instead
Implemented enough of the camera so it can move and project stuff
Now includes string header for memset
Now has xyz enum defined instead of in box
Main now has a game timer which is used to pass into the camera update function
That way it moves based on time
Also now handles extra key presses and then updates the cameras direction
Added timer class
