Fixed automatic insertion of listbullets in Opera FS#1877

The keydown event can't be prevented in Opera (see
http://www.quirksmode.org/dom/events/keys.html) so this switches back to
keypress in Opera (keypress doesn't give the correct key codes in
Firefox). Furthermore Opera replaces '\n' by '\r\n' when inserting text,
thus the offset for cursor/selection placement was wrong.
