Path clearing gadget

A path clearing gadget for engineers, to clear a certain strip from mines and obstacles.
The light green strip is the area that will be cleared from mines only and the darker green is the area that will be cleared from tank obstacles and blocking features (houses, trees, etc.)

The gadget was tested in SP, and will obviously need more thorough testing.

Note that some changes were made to the mine clearing here, so two engineers clear faster together, the old mine clearing was left in place for comparison.
