Expand margins around expander by 3 pixels on each side to make it easier

	* libnautilus-extensions/nautilus-ctree.c (ctree_is_hot_spot):
	Expand margins around expander by 3 pixels on each side to make it
	easier to click the disclosure triangle (triangle will prelight
	when within range), to fix bug 4479


	Fix bugs 4497 (Add configuration option to show only folders in
	tree view) and 2419 (Tree view should track "show hidden files"
	preference):

	* components/tree/nautilus-tree-view.c:
	(nautilus_tree_view_should_skip_file,
	nautilus_tree_view_insert_model_node,
	nautilus_tree_view_remove_model_node,
	nautilus_tree_view_update_model_node): Handle possibly filtering
	out hidden files, backup files or non-directories.

	(filtering_changed_callback,
	nautilus_tree_view_initialize): Initialize from and watch
	filtering preferences, reload whole tree when prefs change.

	(nautilus_tree_view_destroy): Stop watching filtering prefs.

	(reload_model_node, reload_whole_tree, expand_node_for_file,
	nautilus_tree_view_receive_dropped_icons): Update code for
	reloading the tree on expand/collapse etc.

 	* components/tree/nautilus-tree-model.c
	(nautilus_tree_model_directory_files_added_callback): Check if we
	already have a node for each file before trying to create a new
	one. This was needed because otherwise chaning the preference
	settins mentioned above would result in crashes.

	* libnautilus-extensions/nautilus-file.h,
	libnautilus-extensions/nautilus-file.c:
	(nautilus_file_is_hidden_file, nautilus_file_is_backup_file,
	nautilus_file_should_show,
	filter_hidden_and_backup_partition_callback,
	nautilus_file_list_filter_hidden_and_backup): Move hidden file and
	backup file filtering logic here from fm-directory-view.c.

	* src/file-manager/fm-directory-view.c (queue_pending_files): Use
	`nautilus_file_list_filter_hidden_and_backup' to do filtering.

	* libnautilus-extensions/nautilus-global-preferences.h,
	libnautilus-extensions/nautilus-global-preferences.c
	(global_preferences_create_dialog, global_preferences_register):
	Add a new preference for showing only directories in the tree
	view.

	* libnautilus-extensions/nautilus-preferences-dialog.c: Make
	preferences dialog a bit bigger to accomodate the new setting.
