Wrap a (long) text for the value in QLabelElement and QRadioElement

I need to handle a long text as a radio selections.

I introduced the valueLineBreakPolicy property just like the labelingPolicy property.
If the valueLineBreakPolicy property is 'QValueLineBreakPolicyWrap' then 
set detailTextLabel.numberOfLines to 0.
And I changed the super class of QLabelElement from QEntryElement to QLabelElement.
Because QEntryElement uses UITextField to show the value, and UITextFIeld can't handle wrapping text.
