	* lib/ephy-string.c: (ephy_string_collate_key_for_domain):
	* lib/ephy-string.h:

	Add a method to generate collation keys for domain names.

	* src/pdm-dialog.c: (cookie_search_equal),
	(pdm_dialog_cookies_construct), (cookie_host_to_iter),
	(compare_cookie_host_keys), (pdm_dialog_fill_cookies_list),
	(pdm_dialog_cookies_destruct), (pdm_dialog_cookie_add),
	(pdm_dialog_cookie_scroll_to), (sync_notebook_tab),
	(pdm_dialog_init), (pdm_dialog_finalize), (pdm_dialog_open):
	* src/pdm-dialog.h:
	* src/window-commands.c: (window_cmd_edit_personal_data):

	Open the PDM dialogue on the cookies page scrolled to show the
	cookies of the currently loaded page, if there are any. Sort
	cookies by domain. Allow treeview typeaheadfind search to find
	by substring not prefix.
