emv 948fe6ca88 0028747: Incorrect result of the section operation after edge refinement 
Implementation of the method for simplification of the result of Boolean Operation on the API level.
The method BRepAlgoAPI_BuilderAlgo::SimplifyResult has been added, so the derived classes such as BooleanOpeation and Splitter can also use this method.
The result shape simplification should be called after the operation is done. The simplification is performed by the means of ShapeUpgrade_UnifySameDomain algorithm.

Draw command "bsimplify" has been added to control the simplification options.
Documentation for new functionality and draw commands controlling the options of Boolean operations.
Test cases for the new functionality.

Side-effect change:
The algorithms in Boolean component have been changed to use the BRepTools_History as a History tool.
Now it became possible to disable the collection of shapes modifications during Boolean Operations, which may be useful for performance sake (in draw the option is controlled by *setfillhistory* command).
Draw command "unifysamedom" has been changed to accept the angular tolerance in degrees instead of radians.
