ActionBar for AccountFolderList

Displays actionbar properly, and the two buttons work.

Submitting with one open issue:
1.  The indeterminate progress indicator is not directly supported in the
    ActionBar.  We're waiting for a UI call or framework support.  Until
    then there is a placeholder using an incorrect icon to show progress.
