List layout policy (fitpolicy)

Midp2.0 introduces three layout policies:
Choice. text_wrap_on: the part that exceeds the limit is displayed in the next row.
Choice. text_wrap_off: the part that exceeds the limit is ignored.
Choice. text_wrap_default: Default policy, same as choice. text_wrap_on

The setfitpolicy and getfitpolicy methods can be used to set and obtain the current layout policy.
