Added viewpoint scrolling

Now, maps can be larger than (20,15) and the map will scroll as the hero walks across the middle. However, Southward and Eastward middle-traversing appears to warp reality just a little and there are a few kinks that need to be straightened out.

Map layer caching has also been added because the lower and upper layers of a map never change, so they are cached after the first rendering.
