Add option to code QR code with output data in tab separated format

[fuddster]

This allows entry into an Excel (or any?) spreadsheet without need for a VBA script to parse the input.

It will not automatically set up the table or columns, but will make input easier once they are set up.

Caution, the cursor needs to be in the first field of the spreadsheet for it to work correctly.

Will help to have a "Copy Column Names" button, to start the table with column names.

Thanks to Team 2713 - iRaiders for this awesome alternative to VBA parsing.
