Add support for OneDrive vault

[mmarodin]

Have you planned to add the support to store the vault to OneDrive?

Or have you tried to access to OneDrive via webdav protocol? I tried but it doesn't work :( Here an example: https://winscp.net/eng/docs/guide_microsoft_onedrive

Great project! Thanks

In my laptop I can access to the vault from the local folder used by OneDrive. But I have to find a way to access to it from my mobile device (Android/iOS) :)

Let's use this: https://www.npmjs.com/package/onedrive-api

I'd like an entire client built around it, that includes the OAuth side of things as well. Far easier to implement that way. Might be some info here regarding OAuth URLs: https://github.com/onedrivejs/onedrive/blob/master/bin/onedrive-auth
