Clicking radiobutton text can select radio field.

Makes radio buttons have a label, so clicking on the text can choose the option.

There is one visual issue; it looks like the text is automatically put on a new line and not directly aside the radio button. See the image below. Can anyone please assist with a fix for that? Thanks.
