Zettlr: [FEATURE] Moving notes should update markdown references

[mrVanDalo]

• [x] Zettlr does not possess something similar (in which case it
  would be an enhancement, NOT a feature!)
• [x] I have searched the documentation to make sure I did not overlook it.
• [ ] Zettlr's current features cannot be used to approximate this behaviour.
• [x] I have searched all issues (open and closed) to see if someone else
  wants something similar to which I could propose modifications (two
  features in one are easier and faster for us to implement).
• [x] I will prepend "[FEATURE]" to my issue title (this makes the list look much cleaner ;)

Description

When moving a note to a sub-folder or another folder (in the same box), markdown references are not update.

Example Workflow

I have a document zettlr/something.md which contains the markdown reference ![someimage](someimage.png). I also have a file zettlr/someimage.png.
Moving the document zettlr/something.md to zettlr/subfolder/something.md will result in a broken markdown reference.

It would be great if the references would be updated to ![someimage](../someimage.png).

Alternatively zettlr/someimage.png could be moved to zettlr/subfolder but of course it must be assured no other references are broken here.
Maybe magic dialog would help here.

Additional Information

I'm talking about all markdown references, except the [[id]] references which luckily don't have that problem.

Sure, sounds like a good enhancement! I'm on my way of extracting the file parsing logic from the rigid class structures either way, so after this is done it should be a piece of cake to implement this!
