Title: fix LoS

- when a calculation is made to a potentially spotted enemy unit,
but another unit is blocking that LoS, the trajectory stops at
that unit and TileEngine::visible() returns true.
- this fix includes a last check to ensure that the unit that's
attempting to be spotted is really the unit that the trajectory
stops at. If not, return false.
