* make getPropertyList and setPropertyList working for mono valued

  properties :
- added method setPropertyList
- make getPropertyList working on a mono valued property. It will
  return a list of one element (the value of the property)
- make setPropertyList working on a mono valued property, in such
  case a list of one element must be given
- do not generate List methods for mono valued properties any more. 
  List methods were generated for mono valued properties only when 
  some acquisition parameters were defined
- add unit test for getPropertyList and setPropertyList
