Check repository for unarchived links using MementoBear

[refeed]

Unarchived links can be a problem if the site goes down and we can't see the site anymore. We can use MementoBear to handle this problem, it detects unarchived links, and we can submit them to an internet archive service like archive.org to fix the problem.

What happened to this issue? Is it solved yet?

@nvzard @meetmangukiya @refeed Mind if I pick this one up? I need a difficulty/low and this has been stale for over 2 months?

@nvzard @rpanczer I'm sorry, this issue is actually intended to test MementoBear in production, but MementoBear itself needs more optimizations until it stable. So I think I'll keep this one for me until MementoBear stable and ready to use, I still working on MementoBear..
