Smart widget rendering

[Iván Loire]

Come up with some smart way of rendering content on widgets when new data arrives. For example:

• If data didn't change, don't render the widget again (avoid flickering)
• If data changed (and the change is significant for the widget), trigger an effect when rendering (ex: when the number of issues goes down, fadeOut, render new counter, and fadeIn)

React could be handy here (virtual DOM)
