Merged duplicate client/server functions (placed into PMOVETST.C).
PM/SV_RecursiveHullCheck -> HullCheck PM/SV_InitBoxHull -> InitBoxHull PM/SV_HullForBox -> HullForBox PM/SV_HullPointContents > HullPointContents Client now uses WORLDA.S (renamed func) pmtrace_t replaced by trace_t with ent->entnum change pmplane_t replaced by plane_t
