Func e23ec1d0fa Follow-up 76d1135: Use better practice in the code
* The new preference should be prefixed with 'vector'. This is only
  for use in vector skin

* Use registration instead of the hook to set the default user
  preference. For non-dynamic defaults, registration in skin.json
  is preferred.

* Remove the 'wp' prefix for 'hide-if' parameter of field descriptor.
  The core did try to strip the 'wp' prefix when mismatched, which is
  only for backward compatibility.
  Field name without prefix (which is the key of the field descriptor)
  should be used instead.
