[evolution] Add em_folder_tree_model_list_stores().

    Add em_folder_tree_model_list_stores().
    
    Lists all the CamelStores added to EMFolderTreeModel.  Note that
    CamelStores with a corresponding EAccount are only added if the EAccount
    is enabled, so it's safe to assume all returned CamelStores are enabled.
