v1.0.6

Includes a bugfix for a breaking issue where the add-on would throw an error if only metadata is exported.

This release is the first that provides a clean zip file with only the files that are needed.
It also includes a presets zip with the most common and useful export presets.
This should make installation and usage a lot more user-friendly.
Installing the add-on should no longer be done by directly installing the source code zip.
