Setup default widgets when installing
|Reported by:||ryan||Owned by:||azaozz|
A common source of confusion is how the default sidebar that is hard-coded for themes when no widgets are configured "disappears" entirely when go to the widget admin and adding a widget. What is displayed on the front should match what is displayed on the admin. Doing this in a back compat way for all themes is difficult, but we can at least setup some default widgets for the default theme so the out-of-the-box experience for a fresh install is better.
