Activate the found link with a faked keypress event.

2005-08-16  Christian Persch  <chpe@cvs.gnome.org>

	* embed/ephy-embed-find.c: (ephy_embed_find_activate_link):
	* embed/ephy-embed-find.h:
	* embed/mozilla/EphyFind.cpp:
	* embed/mozilla/EphyFind.h:
	* embed/mozilla/mozilla-embed-find.cpp:

	Activate the found link with a faked keypress event.

	* src/ephy-find-toolbar.c: (tab_search_key_press_cb),
	(entry_key_press_event_cb), (entry_activate_cb),
	(ephy_find_toolbar_set_embed), (ephy_find_toolbar_open),
	(ephy_find_toolbar_close):

	On enter, activate the found link instead of finding the next
	occurrence.
	Always really give focus to the find bar, instead of faking
	keypresses in the find bar entry while focusing the embed.
	Fixes bug #307216, bug #311985, bug #312419.
