The Witness: New hint type ("area hints") (#2494)

This new type of "area hint" will instead give you general information about one of the named geographical areas in your world.
Example:

```
There are 4 progression items in the "Quarry" region.
Of them, 2 are for other players.
Also, one of them is a laser for this world.
```

This also renames some of the locations in the game to better fit into an "area", such as the "River Obelisk" being renamed to the "Mountainside Obelisk".
