[evolution/new-importer: 3/3] Bug 599842 - EConfig does not respond to disabling/enabling EPlugins

[Matthew Barnes <mbarnes src gnome org>]

commit 4a47b5aa30de1d374bc3a9518638a60c386e63d7

    Bug 599842 - EConfig does not respond to disabling/enabling EPlugins
    
    Requires eplug files to supply <item type="section"> or
    <item type="section_table"> for this to work.  The container widget's
    "visible" property gets bound to the plugin's "enabled" property.
