Descent 3 by Outrage Entertainment

When activating switches in the room with 6 matcens,
this happens after a short while:
```
Assertion failure at TERRAIN_REGION (Descent3/terrain.h:218), triggered 1 time:

```
The return type of ``BOA_GetNextPath`` is int; but inside the
function, ``false`` is returned, which does not fit the scheme.
Judging from callsites, ``BOA_NO_PATH`` is expected instead.
In some functions related to AI pathfinding, add handling or
assertions for invalid room numbers.
