Title: Depend less on dom-level events for IE < 9

This adds the assumption that all text entry will be accompanied by a keypress event, and adds the guarantee that `handleText()` will never be called on a lone `keydown` event. This is important to avoid conflict with `manager.select()` in IE < 9, where the technique we're using in `hasSelection()` doesn't work.
