fix laggy property models (and probably more)

global fix correcting the initial physics motion state from 0 to 5 (confirm in client). packet captures from a few worlds (didnt scan more than 5 files) show that the value for simple physics was either 5, or 4 for property models, or 1 for property models with behaviors. properties with pre-built models no longer lag and values of physics types should be correct across the board
