Draw_Interpretor, CommandCmd() - catched exceptions and messages put into Tcl string result
before throwing a Tcl exception (return 1) are now print in intense red (using Message::SendFail()).
Duplication of exception message in std::cout and Tcl output has been removed.
Draw Harness plugins have been updated to use either Message::SendFail() or theDI instead of std::cout/std::cerr
for printing colored error message before throwing a Tcl exception.
Protect IntTools_EdgeEdge::FindSolutions method from cases where splitting edge on parts does not give bounding box decreasing.
Use at least Epsilon from edges parameters as a step in BRepLib::FindValidRange.
Test case for the issue.
