Included patch by Simone Rossetto to check if either Python or Perl
are present in the system. Whichever intepreter that is detected
is now used to run the test generator program. If both interpreters
are detected, the CXXTEST_USE_PYTHON variable is obeyed.
Also added support for CXXTEST_TESTGEN_ARGS, for manually specifying
options to the CxxTest code generator.
This adds copyright/license notification blocks CMake's find-modules.
Many of the modules had no notices at all. Some had notices referring
to the BSD license already. This commit normalizes existing notices and
adds missing notices.
