- Fixed mobinfo displaying exp as signed ints rather than unsigned.

- Added status_check_visibility to check if an object is within range of view of another. Nothing more, nothing less. It's used by unit movement to check whether you can continue chasing your target or not when the "chase target" directive is given.
