[FEATURE] Dashboard widgets

[marcjoancr]

Could be great if you add some list of widgets or let the community create some, also you can add like iframe widget in order to add anything you want in the dashboard. I saw this on github the other day: https://github.com/react-grid-layout/react-grid-layout#responsive-usage That idea came from this repo. Maybe it pops up some other ideas for this project or others.
