Fix the long standing bug which caused newly installed GConf

applications to not pick up their default configuration values unless
gconfd-2 was manually restarted. Now:

  - gconftool-2 --makefile-{install|uninstall}-rule will send a SIGHUP
    to all the gconfd-2 processes.
  - upon receipt of that SIGHUP, gconfd-2 will reload the database and
    therefore pick up the added/removed schemas (note that the stock
    gconfd-2 already reloaded the database when receiving a SIGHUP, but
    only in the periodic cleanup which ran every 30 seconds; I've
    modified it to reload the database immediately so that applications
    can be started right after they have been installed).
