New plugin: AutoMOC - find and add missing links

Thank you for your nice plugin! The functionality of this plugin is exactly what I was hoping for.

On the other hand, I think the core function of this plugin is to “link back to all linked mentions quickly,” but I couldn’t immediately notice that from the name AutoMoc. IMHO, it would be better to emphasize that somewhere, because there are other situations where being able to easily link back is useful.

Feature request: if possible, I would like to see a command which creates links to files that has a tag with the same name as the active file name. It would be possible to create a MOC-like page for a tag easily.
