boolean settings from keys "visual_bell" and "audible_bell".
(update_visual_bell_type):
New method to update visual-bell type setting.

New method to convert from gconf string to visual-bell
type enum. Only currently recognized values are "fullscreen"
and "frame_flash".

Also call the update funcs for the new visual-bell gconf keys.
(meta_preference_to_string):
Handle the visual/audible bell cases.
* src/bell.h:
(meta_bell_notify);
New method, calls a visual notifucation
method based on the visual-bell-type, or none if the type
is unrecognized or invalid.
(meta_bell_set_audible):
New public method for setting the audible bell setting,
used in updater for new gconf key "audible_bell".

(meta_bell_set_audible):
If XKB is present, enable/disable the audible system
bell based on the gconf key /desktop/gnome/interface/audible_bell.
(meta_bell_init):
Query and initialize XKB if present, register for notification
on the bell, and set audible bell according to gconf settings.
(meta_bell_flash_screen):
Maps and unmaps a fullscreen X window (painted white, then
black), which causes a fullscreen 'flash' transient.
(meta_bell_flash_window_frame):
Flashes the titlebar of a specified window.

Added scheme information for
/apps/metacity/general/visual_bell,
/apps/metacity/general/audible_bell, and
/apps/metacity/general/visual_bell_type.
2002-12-16 Havoc Pennington <hp@pobox.com>

Tells Metacity how to implement the visual indication that
the system bell or another application 'bell' indicator has
been rung. Currently there are two valid values, "fullscreen",
which causes a fullscreen white-black flash, and "frame_flash" which
causes the titlebar of the application which sent the bell signal to
flash. If the application which sent the bell is unknown (as is
usually the case for the default "system beep"), the currently
focussed window's titlebar is flashed.
