Subject: ENH: remove non/scriptable cmake commands from the script handler in
 ctest, as discussed with David. This also gives a better ctest man page with
 just the commands you should actually use in ctest scripts. Until now these
 commands were more or less executed, but e.g. add_executable() didn't create
 an executable, project() failed with an error. Now you get an error instantly
 if using one of these commands.
