[evolution] EMFolderSelector: Use an ETreeViewFrame.

[Matthew Barnes <mbarnes src gnome org>]

commit a9465c3506ae0310751b5f1503117f0eb8350b4b

    EMFolderSelector: Use an ETreeViewFrame.
    
    Convert the folder selector's "New" button to a [+] button on an inline
    toolbar beneath the folder tree.  The symbolic button looks better, and
    clicking it no longer triggers a "response" signal, which terminates a
    gtk_dialog_run() call.  We don't want gtk_dialog_run() to terminate in
    this case.
