[lmi] [PATCH] Add --gui_test_path command line option to the GUI test.

[Vadim Zeitlin]

 Here are the patches adding the promised --gui_test_path option. The first
one is just some minor cleanup, the second one is the important one, the
third one updates the benchmark test (I decided to do it in a separate
commit as it's not really related to the rest of changes) and the last one
removes the config file handling which becomes unnecessary after the
previous change.

 Just FYI here is how running the benchmark census test looks right now:

        % ./wx_test.exe --data_path=/opt/lmi/data --gui_test_path=/opt/lmi/test 
-t benchmark_census
        NOTE: starting the test suite

        time=52621ms (for benchmark_census)
        benchmark_census: ok
        time=52621ms (for all tests)
        SUCCESS: 1 test successfully completed.
 
Notice that there is no error -- nor even warning -- if no MSEC*.cns files
are found. I decided that it would be visible enough anyhow in the output
as the benchmark_census test execution time would be more or less 0 then,
but please let me know if you think it's worth adding a warning in this
case.

 Also, in addition to the (optional) MSEC*.cns files, the test directory
must currently contain CoiMultiplier.cns (used by the input_validation
test), PasteCensus.cns (used in the paste_census one), MonthlyTrace.ill
(output_validation_illustration) and MecTesting.mec (output_validation_mec).
At least PasteCensus.cns will become unnecessary soon, but this will be
part of another patch.

 As always, please let me know if you have any questions about any of the
changes here and thanks in advance for applying them!
