3a7c8d1f32 BulletSim: the minimum vehicle velocity was set too low so moving slow 
was getting zeroed too easily. Added VehicleMinVelocity parameter.

766a31431e BulletSim: implement the SL bug where VEHICLE_HOVER_UP_ONLY disables 
the vehicle buoyancy if the vehicle is above its hover height.

This is a known misfeature of this vehicle flag which has been accepted
since it would break too many implementations. The problem is noticed
when creating a jetski-like vehicle that jumps over sand bars. A boat
normally is configured with neutral buoyancy and hovering at water
height. When it jumps the sandbar, it needs to have gravity applied
to get back to water level.

b4c3a791aa BulletSim: move collision processing for linksets from BSPrimLinkable 
into the linkset implementation classes.
Add HasSomeCollision attribute that remembers of any component of
   a linkset has a collision.
Update vehicle code (BSDynamic) to use the HasSomeCollision in place of
   IsColliding to make constraint based linksets properly notice the ground.
Add linkset functions to change physical attributes of all the members
   of a linkset.

2c761cef19 BulletSim: add parameter to optionally disable vehicle linear deflection. 
Add parameter to not apply vehicle linear deflection Z forces if
vehicle is not colliding. This defaults to 'true' so vehicles will fall
even if there is some linear deflection to apply.

fad4241e4e BulletSim: make all the different angularVerticalAttraction algorithms 
selectable from configuration paramters.
Changed default algorithm to "1" from previous default as it seems to
handle Y axis correction a little better.
Add config file independent enablement of vehicle angular forces to
make debugging easier (independent testing of forces).

045aaa838a BulletSim: remove friction calcuation from BSMotor and move linear and 
angular friction computation into linear and angular movement code.
The friction wasn't being applied properly. This will make it so vehicles
don't drift as much and the drift is tunable by changing the friction
timescales.
