rigid: main finding is rigid needs to take delta into account for integration (aka interpolation)
also used POINT_EPSILON for thresholds for consistency
for rigidshape/item/player, main finding was length calcs for the search area were all over the place,
so we now derive the extended length of the cached area based on the velocity and the object's radius itself rather than guessin per class
atrest gravity calc suplimental syncing between rigidshape and vehicle
**remindernote POINT_EPSILO is 0.0001
clustering work for datablocks for both consistent scanning for object parameters, as well as an eye towards orgainizing things to make reviewing what variations of components we'll be needing down the line clearer
1) got rid of evey class having it's own gravity
2) rigidshape inheritance simplifications
3) gravitymod from physicszones taking buoyancy into account natively (we still track raw bouyancy to cancel it out for player)
4) disableMove used throughout
5) items can now also be influenced by the appliedforce from physicszones
- Con::executef now uses a template
- All public execution functions now restore the console stack upon return
- Fixed bad parameters on some callbacks
- Reverts get*Arg behavior
