xF1 Unmaintained [TH] Import Tools 1.0.1

What does this add-on do?
This add-on adds a number of new options when performing an import from another forum software.

By allowing you to undo steps, skip steps and recover previous imports, and by skipping over any IDs that have previously been imported when you run a step more than once, this add-on makes debugging an importer or performing a staged import easier than ever.

This add-on is an advanced tool. Always backup before performing an import. It is also recommended to run a full test import first before completing an import for real.
