Adds some files to remove in manifest files
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
