Subject: Add event type to the callback.

2006-01-17  Christian Persch  <chpe@cvs.gnome.org>

	* lib/ephy-file-helpers.c: (ephy_file_monitor_timeout_cb),
	(ephy_file_monitor_cb):
	* lib/ephy-file-helpers.h:

	Add event type to the callback.

	* embed/mozilla/EphyUtils.cpp:
	* embed/mozilla/EphyUtils.h:

	New function, like NS_NewFileURI (which we can't use since
	nsNetUtil.h conflicts with embed strings).

	* embed/mozilla/mozilla-embed-single.cpp:
	* embed/mozilla/mozilla-notifiers.cpp:

	Check that the user CSS file exists before registering it.
	Also handle file-deleted events.

	* src/bookmarks/ephy-bookmarks-menu.c: (ephy_bookmarks_menu_build):
	* src/bookmarks/ephy-topics-palette.c:
	(ephy_topics_palette_constructor),
	(ephy_topics_palette_class_init):

	Build fixes.
