Fixed bug with option fields.

If the addOptions() method was used on RadioField or SelectField, and the array was provided as numeric, it would wrongly get added as numeric and values would not be associated correctly with their options. This was especially troublesome for the first element in the options array, as that element would be impossible to select.
