read signed shorts. fix brush and copy/move

-a volume might contain cells with negative coordinates which r
 also important.
 using the brush tool or copy/move tool can cause a part of the
 structure to be out of bounds and thus contain negative coords.
 we need the exact same coords to correctly generate the volume
 structure when receiving the packet.
 (structures r sliced off at world boarder when generating but we
 need all cells and their correct coordinates to generate accurate
 proportions of the structure
