Add dashboard widget to show the latest notes. Issue #51

p.s: I would like to be able to select a particular tag to show, but
none of the dashboard widgets are configurable.

I hate increasing the app size from 300k to almost 3 mb for something
so simple, but we must adapt to the majority and use vue here.
