[cp-patches] Patch: RadioButton fix

[Lillian Angel]

- Adjusted RadioButton demo, to demonstrate a button group.
- Also, fixed ButtonGroup so that any newly added item that is selected,
sets the 'sel' variable. Otherwise, if it is not initialized here there
is a possibility a user can selected 2 radio buttons at once.
