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.
