Removed primary action button from theme's Add Widget page

Widgets editor will get sort order right when sorting within the same widget area

Themes dashboard revisions. Can now Activate, Clone, and Delete themes from the themes dashboard. Added a store picker to the themes dashboard as well. Themes active on another store will show the list of stores they are active on.
