A couple of inside()-related cleanups.

Browse source 
- make inside_editor() static in build.c
- replace comparisons of inside()'s return values with 0 by ones with 1
  (since a returned 0 can mean -1 or 1, i.e. oob sector or is really inside)
- prevent a theoretically possible oob access in correct_ornamented_sprite()
