Create machinery to treat/deal with case of empty rows on an Airtable tables

[Hugemiler]

Sometimes, it is possible that our manual edits into Airtable end up generating a fully-blank row on tables like Subject or Aliases, etc.

Current state when parsing the local-sourced JSON file is to throw error:

While running Localbase().

We need to be able to handle those cases. Maybe warn() and skip, or build a more informative error message.
