Make sure all the default source groups and sources are present by adding

2005-02-19  Sivaiah Nallagatla <snallagatla@novell.com>

        * gui/calendar-component.c (ensure_sources) :
        Make sure all the default source groups and sources
        are present by adding missing ones. Also update the
        base uri of "On This Computer" group to take care
        of change in user home dir.
        (calendar_component_init) : call ensure_sources

        * gui/tasks-component.c (ensure_sources)
        (tasks_component_init) : ditto

        Takes care of #67411 & #67724 for
        calendar and tasks components.
