Add mega cloud drive support for vault sync.

Please consider adding mega drive support for vault sync like it has for dropbox.

We've previously rejected Mega support, as you can see here. That being said, I'd consider adding it if there's enough interest or if someone contributes the support in core.

I would also be very interested in adding Mega for vault sync!! I just dropped Dropbox for Mega, which gives much better support to opensource and esp. linux environments, beside that it is a zero-knowledge cloud service, of course.
