Log message:
- added "add option" to the combo box
A combo box is one of the new compound form element types.
It consists of a select box, a text input field and an optional
"add option" button. If the user hits the "add option" button the new
option gets inserted at the beginning of the select box option list.
Warning: the form API for Combo boxes might change slightly in future
versions.
- updated the demo
