Thanks to @Steffen who reported and provided patches for a significant number of these changes (y)

This version includes the functionality extensions from 1.1.0 and adds a fix for the error that can occur when copying posts from one thread to another existing thread.

Following suggestions from @Steffen, the redirect add-on will now support a collection of non-content links that may be commonly referrered to in user generated content.

This version catches the error that is (intentionally) thrown when a redirect is attempted prior to the import log table having been configured.

The exception is still logged to the admin server error log.

Previously, this add-on excluded XFMG tables from its list available for selection as the import log table, but this added an unnecessary dependency, so I've removed it.

This version won't throw an error when you point it to an import table generated by XenForo 1.
