* Terrain modification more robust, uses area sizes matching those employed by the client display.

* Terrain tools now account for the duration the cursor was held for.
* Terrain tools now support new brushes (completing the common set)
** Smooth brush
** Flatten brush
** Revert brush
** Noise brush
