because of some changes on the FieldText widget to correctly compute the
size of the eidt box, the SmsWidget can no longer extend that widget since
we work with a DIV and not a single TEXTAREA. For the future, we
might change the way FieldText works but since we only need the basic
functions from InputField in this case (no need of resize nor
translations) we chose to extend InputField.
