This patch introduces simple help() function, which can either display man page for lmishell (if installed), or pydoc help for an object.
See following example:
> help
Type help() to see man page for lmishell, or help(object) for help about object.
> help()
... man page ...
or
Man page for lmishell can not be found, refer to Wiki page instead.
