[V3 Help][ fix help_formatter to obey length limits (#1375)

Browse Source 
Help didn't account for docstrings passing length limits which I noticed a while ago and as noticed again when Palm forgot a dual newline in a command docstring.
This PR sees to fix this by enforcing length limits on description, field names and field values
