Task 518. Support for changing preferecens individually

within each confgurable user level.

* libnautilus-extensions/nautilus-global-preferences.h:
Change all preferences strings to not include the "/nautilus"
prefix.  The prefix is not automatically computed by the prefences
api taking into account the user level.

Add (nautilus_global_preferences_dialog_update) to rebuild the
preferences dialog when the user level changes.

* libnautilus-extensions/nautilus-global-preferences.c:
(global_preferences_get_dialog),
(global_preferences_register_sidebar_panels_preferences_for_ui),
(global_preferences_register_with_defaults),
(global_preferences_register_boolean_with_defaults),
(global_preferences_register_string_with_defaults),
(global_preferences_register_enum_with_defaults),
(global_preferences_register_for_ui),
(global_preferences_initialize_if_needed),
(nautilus_global_preferences_show_dialog),
(nautilus_global_preferences_hide_dialog),
(nautilus_global_preferences_set_dialog_title),
(nautilus_global_preferences_dialog_update),
(nautilus_global_preferences_shutdown):
remove the user level tracking hack.  We now set default values
for each of the user levels.

* libnautilus-extensions/nautilus-icon-container.c:
(nautilus_icon_container_initialize):
Simplified preference callback api by having a single add_callback
function.  Use it here.

* libnautilus-extensions/nautilus-list.c:
(nautilus_list_initialize):
Simplified preference callback api by having a single add_callback
function.  Use it here.

* src/file-manager/fm-directory-view.c:
(fm_directory_view_initialize):
Simplified preference callback api by having a single add_callback
function.  Use it here.

* nautilus-widgets/nautilus-preference.c:
(preference_initialize_if_needed), (preference_hash_node_alloc),
(preference_hash_node_free_func), (preference_hash_node_free),
(preference_register), (preference_hash_node_lookup),
(preference_hash_node_lookup_with_registration),
(nautilus_preference_shutdown), (nautilus_preference_find_by_name),
(nautilus_preference_set_info_by_name),
(nautilus_preference_enum_add_entry_by_name):
* nautilus-widgets/nautilus-preference.h:
Move the preference description hash table here from
nautilus-preferences.  These are preferences that are expected to
have nice defaults as well as descriptions and possibly extra data
for the preferences widgets to use (like enumeration values)

I moved the tabulation and hashing stuff intactly even though it
contains many turds.  I plan to fix these soon.

* nautilus-widgets/nautilus-preferences-group.c:
(nautilus_preferences_group_add_item):
* nautilus-widgets/nautilus-preferences-item.c:
(preferences_item_construct), (enum_radio_group_changed_callback):
Update for the above.

* nautilus-widgets/nautilus-preferences.c:
(preferences_hash_node_alloc), (preferences_hash_node_free),
(preferences_hash_node_add_callback),
(preferences_hash_node_remove_callback),
(preferences_hash_node_check_changes_func),
(preferneces_callback_node_invoke_func), (preferences_register),
(preferences_hash_node_lookup_with_registration),
(preferences_gconf_callback), (user_level_changed_callback),
(preferences_initialize_if_needed),
(nautilus_preferences_add_callback),
(nautilus_preferences_set_boolean),
(nautilus_preferences_get_boolean),
(nautilus_preferences_set_enum), (nautilus_preferences_get_enum),
(nautilus_preferences_set), (nautilus_preferences_get),
(nautilus_preferences_shutdown):
* nautilus-widgets/nautilus-preferences.h:
Move the tabulation of nice preferences to nautilus-preference.

Install one gconf notification for each user level.  Remove all
the extra unused registration parameters.

Use generated keys that take into account the current user level
to communicato with GConf.

Keep track of user level changes so that we can compare
preferences between user levels and fire callbacks accordingly.
This simplifies the lifes of preferences callers as they can
continue to install one simple callback as before.  They will get
notified when a preference changes for whatever reason.  That
could be the user manaually tweaking it, or a sweeping user level
change.

Again, i tried to keep as much of the original hashing logic
intact.  It needs cleaning up as well.

* nautilus-widgets/nautilus-user-level-manager.c:
(nautilus_user_level_manager_set_default_value_if_needed),
(nautilus_user_level_manager_compare_preference_between_user_levels
):
* nautilus-widgets/nautilus-user-level-manager.h:
Add a public function to determine whether a preference is the
same between 2 user levels.

* nautilus-widgets/test-nautilus-preferences.c:
(register_global_preferences):
Update to reflect api changes.

* src/nautilus-window-menus.c: (nautilus_window_initialize_menus),
(user_level_changed_callback),
(get_customize_user_level_setttings_menu_string),
(update_preferences_dialog_title):
Update the preferences dialog whenever the user level changes.
This is an easy way to have the dialog reflect reallity.

It would be a lot nicer it the contents updated on the fly instead
of rebuilding the whole thing.  I can do that later.
