[empathy: 4/8] Make the empathy-account code be slightly more streamlined

[Sjoerd Simons <sjoerds src gnome org>]

commit b0de7c5d5d8c93dd7b74a77b4892c331f37f5441
Author: Sjoerd Simons <sjoerd simons collabora co uk>
Date:   Mon Mar 1 18:59:38 2010 +0000

    Make the empathy-account code be slightly more streamlined
    
    On every run of the accounts UI we should try to import MC4 accounts (if they
    weren't imported already). Also replace the --try-import option with
    --if-needed to better document the fact that it will only display the UI if
    needed.
