GUI: manage printed output when running an IODE report

@jmpplan I ma looking for a way to manage the printed output when a user is running an IODE report.

Below the output printed when running the IODE report rep_fns.rep from the the /tests/data folder:

Running report C:/usr/Projects/iode-1/tests/data/rep_fns.rep ...

C:/usr/Projects/iode-1/tests/data/rep_fns.rep[7] - $indent
C:/usr/Projects/iode-1/tests/data/rep_fns.rep[8] - $goto continue 0
C:/usr/Projects/iode-1/tests/data/rep_fns.rep[9] - $show Syntax: rep_fns input_dir output_dir
Syntax: rep_fns input_dir output_dir
C:/usr/Projects/iode-1/tests/data/rep_fns.rep[10] - $show Syntax error. Report aborted.
Syntax error. Report aborted.
C:/usr/Projects/iode-1/tests/data/rep_fns.rep[11] - $return

Execution of report C:/usr/Projects/iode-1/tests/data/rep_fns.rep: Successful

In particular, I would like to print "rep_fns.rep[..]" instead of the full path to the report.

Note:

1. I pass the absolute path to C++ function execute_report() (which calls B_ReportExec()) for some technical reasons and I very would like to continue to pass the absolute path.
2. The report contains the directive $debug 1
