David Steele c5157c0334 Automatically generate constants for command and option names.
These constants are easier than using cfgOptionName() and cfgCommandName() and lead to cleaner code and simpler to construct messages.

String versions are provided. Eventually all the strings will be used in the config structures, but for now they are useful to avoid wrapping with strNew().
