Ensure Obsidian link-updating-after-moving works with the current markdown link formats

[GSGBen]

If it doesn't, add an option to use Obsidian link formats (wiki) instead.

Mostly. Make the attachment title the attachment name instead as it doesn't get updated.

Then test moving a whole folder.

Hmmm, when it updates the files it breaks the image-within-link from #37. See if that happens with wiki links.

I can't get the inside to work with wiki-links. Instead: try moving the file link to a different column.

That worked.
