Also add GameSave::PressureInTmp3 to check for elements with pressure memory and fix TUNG not sampling pressure on creation. This does not in itself fix#822 because tmp3 and tmp4 are still saved in 16 bits each, so full ctypes still don't fit in tmp3.
The rest will will in a commit soon that adds the Create event and some other stuff
Lua events will come after that
PLSM default temp lowered to MAX_TEMP
