v6.0.0

This release is a complete re-write of the back-end logic that powers this script. The main goal was to organize functions into namespaces and write tests to verify some core functionality.

This rewrite resulted in several bug fixes:

• Scripts will no longer silently fail to restart after hitting their maximum runtime of 90 minutes. Now they will automatically sleep for 24 hours to reset the Google Quota and then restart automatically
• Fixed a bug when searching for folders when the URL contained extra URL params
• Fixed a bug due to a newer version of Spreadsheets that would occasionally fail to add values to a spreadsheet when there was not a blank row to write to. Now it inserts a blank row by default.
• Dramatically simplified and improved the process for saving the runtime properties. This should result in more consistency and fewer JSON parse errors.
