- fixed some places in p_pillar.cpp where sector plane z's were calculated at (0, 0) which could cause overflows if the actual plane is too far away from the origin.

- renamed sector_t::soundorg in centerspot, changed the type to a fixedvec2 and removed the CenterSpot #define.

Since this thing was used in lots of places that have nothing to do with sound the name made no sense. Having it as a fixed_t array also made it clumsy to use and the CenterSpot #define used a potentially dangerous type cast.
