[evolution/webkit] Let EMFolderSelector create its own EMFolderTree.

[Dan VrÃtil <dvratil src gnome org>]

commit 925f1dc581745554d6251a3bd25a7aa9795b10bc
Author: Matthew Barnes <mbarnes redhat com>
Date:   Mon May 23 22:42:49 2011 -0400

    Let EMFolderSelector create its own EMFolderTree.
    
    Also, minimize the EMFolderSelector API by removing frivolous wrapper
    functions and unused functions.
