room: test sector range for Torso boss (LostArtefacts#1497)

This provides an option to test a range of sectors around the one on
which a large and heavy item dies. It ultimately resolves the potential
softlock when killing Torso boss in Great Pyramid.

Resolves LostArtefacts#1236.

 - changed `/tp` console command to look for the closest place to teleport to when targeting items (#1484)
 - improved appearance of textures around edges when bilinear filter is off (#1483)
   Since this removes the seams on pushblocks, this was made optional.
