v3.4.20 Export MSForms 2.0 form design as JSON

Enhancements

• While rarely used in Microsoft Access, traditional VBA forms (Microsoft Forms 2.0) can be used in Microsoft Access databases. This update adds an additional exported source file (for reference) which shows the form design in human readable JSON format. See #297 for details.

Bug Fixes

• Switching from a local table to a linked table with the same name can create an orphaned file in tbldefs. This caused build errors when the add-in attempted to import both the local and linked versions of the table. Thanks @jhgarrison for pointing this out! #296
