Title: Allow enemies to wander randomly in a rectanglular area

To use this feature, add the following to an [enemy] definition in a map file:

```
wander_area=48,48,4,4
```
The first two values are the x and y values corresponding to the top-left tile of the rectangle. The next two values are the width and height of that rectangle (in tiles).
