Clientmap: Define p_nodes_min/max as v3s32 instead of v3s16
'cam_pos_nodes -/+ box_nodes_d' can exceed the range of v3s16 when a player is near the world edge using a large view range This previously caused world to disappear Create new function getBlocksInViewRange() called from updateDrawList() and renderMap() Correct code style throughout updateDrawList() and renderMap()
