MarkEdit crashes on Catalina

[cooljeanius]

To reproduce, open any markdown file with content in it and then try editing it with MarkEdit. After a few keypresses MarkEdit will eventually crash. Here is an example backtrace from the crash dialog:

@bodhi this still happens on Big Sur... it's not that big of a deal since I've found another Markdown editor, but if you're not going to maintain this repository any longer, you should at least mark it as archived, to prevent any further issues activity

[bodhi]

@cooljeanius terribly sorry about this. I actually wanted to get it working again, but the yak shaving of dependency updates to get it building again was too much for me at the time.

Yes, that's a good idea, I'll do this.
