RB.Admin.WidgetView now has utility functions for adding header/footer

actions, allowing subclasses to focus on the content of the action and

not the DOM structure. This also simplifies templates, meaning that most

widgets won't even need a custom template anymore.
Widgets do provide an optional built-in action for reloading content. If

a subclass sets canReload to true, the action will be added, and a

reloadContent() method will be called when clicked. Implementations of

this can make use of a setReloading() method that controls a spin

animation for the reload action. Some upcoming widgets will take

advantage of this.
Styling improvements have been made to help the actions stand out

better, and to set better sizes of FontAwesome icons used for actions.

Made use of this in the News widdget.
