created saves directory, Game properly saves/loads player data in a pickle object
decided not to track saves folder because pickle files will change too often, set up proper drawing for player and movement for player
 removed saves directory from git repo
added x, y, surface, and rect member variable to Terrain class, added draw and reloadSurface funtion
Game succussfully creates a grassy background for the player to move around in
fixed screen size so that it ties to the MAX_X  and MAX_Y constants, adjust TerrainGenerator so that it uses Tiles instead of the Terrain directly
current level is now saved to name passed to Game at beginning, level is also loaded from same file
added Camera class to allow for scrolling, not quite working yet
