Request for App: Name Auto-renewal App

[pstan26]

It would be nice to have a desktop tool that could periodically run blockstack whois to see which of your names need to be renewed. If a name is getting close to expiration, the tool should let the user know so they can run blockstack renew (e.g. via desktop notification, via email, via SMS, whatever).

A slightly more advanced version would automatically renew the name.

This is an interesting problem, because renewal can't be put off until the last second (lest your transaction get stuck in a backlog for example). I personally would do my renewal no less than a month in advance.

(his task is moved from: https://github.com/blockstack/sample-apps/issues/3 since we renamed another repo with a more appropriate name)
