Don't open search toolbar on / or ' over formfields:

2005-06-03  Christian Persch  <chpe@cvs.gnome.org>

	Don't open search toolbar on / or ' over formfields:

	* embed/ephy-embed.c: (ephy_embed_base_init):
	* embed/ephy-embed.h:

	New signal for searchable key presses.

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

	Add static function to check if a keypress should be forwarded
	to the search toolbar.

	* embed/mozilla/mozilla-embed.cpp:

	Emit the signal here.

	* lib/ephy-marshal.list:
	* src/ephy-find-toolbar.c: (tab_search_key_press_cb),
	(ephy_find_toolbar_set_embed):

	Use the new signal instead of dom-key-press.
