PATH-842, VWR-29431: BUGFIX Correcting a regression introduced by the fix for PATH-542.  The viewer calculated rotation resulting from an object's angular velocity was being incorrectly reset when the corresponding object update was received.  With this bugfix, the rotation resulting from the angular velocity is accumulated separately and is re-appplied when the object update resets the object's rotation.

Path-643. Once the preferences panel is closed (either through ok or cancel), the pathing console rebuilds the gfx data.

Setting the description column of the linkset floater to be a fixed width.  Having multiple dynamic width columns apparently prevents other columns from being manually resized by the user.
