ENH:

-in the full documentation there is now an extra section for
compatibility commands, so users see which commands they shouldn't use
-cmake -h <command> now also works with lower case commands
--help-fullm --help-command, --help-module and --help-property now determine
the output format from the extension of the given filename

Let me know if there are some things I overlooked.
