fixed component.isRobot (tho that's deprecated anyway!); reworked machine state saving - kernel (and stack, if necessary) are now saved in extra files instead of in the tile entity's nbt tag. if the data gets too bit, minecraft apparently silently fails in saving the chunk... yay. the kernel data is dumped uncompressed to saves/[world]/opencomputers/[chunkX].[chunkY]/[node_address]_kernel - uncompressed because gzipping makes saving noticeably slower. this also allows removing the waila check in the save in case people still have a very old version of it.
