jForm - improvements on the checkbox control: values label

We can now declares labels to use when we want to display
the value of the checkbox. These labels are displayed
instead of the value.

We can declare them using new tags: oncheckvalue and onuncheckvalue:

   <checkbox ref="geek">
      <label>Are you a geek ?</label>
      <oncheckvalue label="yes" />
      <onuncheckvalue label="no" />
   </checkbox>

these new tags supports also these attributes:
- locale: to indicate a locale instead of a label
- value: to indicate the value when it is check or not. It
 replaces values indicated into valueoncheck or valueonuncheck
Improvement on formadata + fixed issues on latest enhancements

formdata plugin accepts now the name of a jforms builder
and options for this builder.
jforms - possibility to display a specific label for empty value

When the value of a control is empty, we can now have the possibility to indicate a label,
that will be used when showing the control with ctrl_value.
This is a new emptyvaluelabel element in the xml file.
