Check that the chain of deferences in gui->account->source->url is safe.

	* mail-account-gui.c (source_type_changed): Check that the chain
	of deferences in gui->account->source->url is safe.  This was
	causing a segfault when adding a new account if any of the
	existing accounts had their sources set to "None".
	(i.e. gui->account->source == NULL)

	* mail-accounts.c (load_accounts): Check that account->source !=
	NULL before dereferencing it.
	(load_accounts): The selection is cleared when the account clist
	is rebuilt (say after a call to add), but no unselect event is
	emitted.  Yes, the clist is evil.  We work around this by
	explictly calling mail_unselect, our unselect signal handler.
	(Otherwise, the edit and delete buttons remain sensitive and
	accounts_row != 0, but the user can't see which row the dialog
	thinks is selected.)
	(load_news): Check the account->source != NULL before
	dereferencing it.
	(mail_unselect): If an insensitive button in a button box has the
	focus, and if you hit tab, there is a segfault deep inside of gtk.
	This is probably a gtk bug.  We work around it by having the add
	button (which is always sensitive) grab the focus on an unselect.
