[PATCH V3 3/5] Help.c add --guide option

[Philip Oakley <philipoakley@iee.org>]

Logic, but no actions, included.

The --all commands option, if given, will display first.
The --guide option's list will then be displayed.

The common commands list is only displayed if neither option,
nor a command or guide name, is given.
