/* todo (in order of importance):
    - don't crash when the plugin gets unloaded (it seems to crash after
       the plugin has gone, when gtk updates the button in the plugins
       dialog. backtrace is always useless. weird)
    - handle and update tooltips to show your current accounts
    - dernyi's account status menu in the right click
    - store icons in gtk2 stock icon thing (needs doing for the whole prog)
    - optional pop up notices when GNOME2's system-tray-applet supports it
    - support blinking the icon when messages are pending */
